Question

What is the answer 4a + 7​

Answer 1

Simplifying

4a + -7 = 13

Reorder the terms:

-7 + 4a = 13

Solving

-7 + 4a = 13

Solving for variable 'a'.

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

Add '7' to each side of the equation.

-7 + 7 + 4a = 13 + 7

Combine like terms: -7 + 7 = 0

0 + 4a = 13 + 7

4a = 13 + 7

Combine like terms: 13 + 7 = 20

4a = 20

Divide each side by '4'.

a = 5

Simplifying

a = 5
