y = 3x + 3

y = 1/2x + 6

1 answer

To solve this system of equations, we can set the two equations equal to each other since they both equal to y:

3x + 3 = (1/2)x + 6

Now let's simplify the equation:

2(3x + 3) = 2((1/2)x + 6)
6x + 6 = x + 12

Next, we can subtract x from both sides:

6x - x + 6 = x - x + 12
5x + 6 = 12

Now, let's subtract 6 from both sides:

5x + 6 - 6 = 12 - 6
5x = 6

Finally, to isolate x, divide both sides by 5:

(5x)/5 = 6/5
x = 6/5

To find the corresponding y-value, substitute x = 6/5 into either of the original equations. Let's use the first equation:

y = 3(6/5) + 3
y = 18/5 + 15/5
y = (18 + 15)/5
y = 33/5

Thus, the solution to the system of equations is x = 6/5 and y = 33/5.
