Answer:

-13=x

Step-by-step explanation:

4(-13)-10=-42

-52-10=-42

Answer:Simplifying

4x + -10 = 42

Reorder the terms:

-10 + 4x = 42

Solving

-10 + 4x = 42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 4x = 42 + 10

Combine like terms: -10 + 10 = 0

0 + 4x = 42 + 10

4x = 42 + 10

Combine like terms: 42 + 10 = 52

4x = 52

Divide each side by '4'.

x = 13

Simplifying

x = 13
