We can set up an equation to solve for the number of weeks it will take for Miguel and Christina to have the same amount of gas in their tanks.
Let's say x is the number of weeks that have passed.
Miguel's gas used in x weeks: 1.5x
Christina's gas used in x weeks: 1x
Now we can set up the equation:
20 - 1.5x = 16 - 1x
Simplifying the equation:
2 = 0.5x
Dividing both sides by 0.5:
x = 4
Therefore, it will take 4 weeks for Miguel and Christina to have the same amount of gas in their tanks.

To solve the equation:
11x = 3(7x - 1) - 10x
Start by distributing the 3:
11x = 21x - 3 - 10x
Combine like terms:
11x = 11x - 3
Subtract 11x from both sides:
0 = -3
Since this results in a false statement (-3 = 0), there is no solution.
Therefore, the equation has no solution.
11x = 3(7x - 1) - 10x
Start by distributing the 3:
11x = 21x - 3 - 10x
Combine like terms:
11x = 11x - 3
Subtract 11x from both sides:
0 = -3
Since this results in a false statement (-3 = 0), there is no solution.
Therefore, the equation has no solution.

To solve the equation:
5(2x + 2) - 4 = 2x + 6
Start by distributing the 5:
10x + 10 - 4 = 2x + 6
Combine like terms:
10x + 6 = 2x + 6
Subtract 2x from both sides:
8x + 6 = 6
Subtract 6 from both sides:
8x = 0
Divide both sides by 8:
x = 0
Therefore, the equation has one solution: x = 0.
5(2x + 2) - 4 = 2x + 6
Start by distributing the 5:
10x + 10 - 4 = 2x + 6
Combine like terms:
10x + 6 = 2x + 6
Subtract 2x from both sides:
8x + 6 = 6
Subtract 6 from both sides:
8x = 0
Divide both sides by 8:
x = 0
Therefore, the equation has one solution: x = 0.
Solve the following linear equation for x. Then check your answer. Show all your steps for solving and checking.
5x+8+x=32
5x+8+x=32
To solve the equation:
5x + 8 + x = 32
Combine like terms:
6x + 8 = 32
Subtract 8 from both sides:
6x = 24
Divide both sides by 6:
x = 4
To check the answer, substitute x = 4 back into the original equation:
5(4) + 8 + 4 = 32
20 + 8 + 4 = 32
32 = 32
Since both sides are equal, the solution x = 4 is correct.
5x + 8 + x = 32
Combine like terms:
6x + 8 = 32
Subtract 8 from both sides:
6x = 24
Divide both sides by 6:
x = 4
To check the answer, substitute x = 4 back into the original equation:
5(4) + 8 + 4 = 32
20 + 8 + 4 = 32
32 = 32
Since both sides are equal, the solution x = 4 is correct.
