13 - 2(1 - 15) ÷ 4 simplifies to 13 - 2(-14) ÷ 4.
Next, we simplify the multiplication first, so 2(-14) = -28.
Now, we have 13 - (-28) ÷ 4.
We continue the simplification by dividing -28 by 4, which gives us -7.
Finally, we have 13 - (-7) = 13 + 7 = 20.
Therefore, the simplification of the expression 13 - 2(1 - 15) ÷ 4 is 20.

Solve for x.
−5x+2=67
−5x+2=67
To solve for x, we need to isolate x on one side of the equation.
Starting with the equation -5x + 2 = 67:
First, we subtract 2 from both sides of the equation to get -5x = 65.
Then, we divide both sides of the equation by -5 to solve for x.
This gives us x = -13.
Therefore, the solution for x is -13.

(2x+2)−(3x+11)
To simplify the expression (2x + 2) - (3x + 11), we need to distribute the negative sign to each term within the parentheses. This can be done by changing the sign of each term inside the second parentheses:
2x + 2 - 3x - 11
Next, combine like terms. In this case, combine the x terms and the constant terms separately:
(2x - 3x) + (2 - 11)
Simplifying further:
-x - 9
Thus, the simplified expression of (2x + 2) - (3x + 11) is -x - 9.
2x + 2 - 3x - 11
Next, combine like terms. In this case, combine the x terms and the constant terms separately:
(2x - 3x) + (2 - 11)
Simplifying further:
-x - 9
Thus, the simplified expression of (2x + 2) - (3x + 11) is -x - 9.
What is the first step in solving the equation:
20=6x−4
20=6x−4
The first step in solving the equation 20 = 6x - 4 is to isolate the variable term, in this case, 6x.
To do so, we add 4 to both sides of the equation:
20 + 4 = 6x - 4 + 4
This simplifies to:
24 = 6x
Now we can proceed to solve for x by dividing both sides of the equation by 6:
24/6 = 6x/6
This simplifies to:
4 = x
Therefore, the solution to the equation 20 = 6x - 4 is x = 4.
To do so, we add 4 to both sides of the equation:
20 + 4 = 6x - 4 + 4
This simplifies to:
24 = 6x
Now we can proceed to solve for x by dividing both sides of the equation by 6:
24/6 = 6x/6
This simplifies to:
4 = x
Therefore, the solution to the equation 20 = 6x - 4 is x = 4.
