Question

What is the value of x in this equation

Answer 1

The the first one the answer should be -4

For the second one the answer should be 3

Answer 2

Answer: Simplifying

4a + 3(a + 1) = 24

Reorder the terms:

4a + 3(1 + a) = 24

4a + (1 * 3 + a * 3) = 24

4a + (3 + 3a) = 24

Reorder the terms:

3 + 4a + 3a = 24

Combine like terms: 4a + 3a = 7a

3 + 7a = 24

Solving

3 + 7a = 24

Solving for variable 'a'.

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

Add '-3' to each side of the equation.

3 + -3 + 7a = 24 + -3

Combine like terms: 3 + -3 = 0

0 + 7a = 24 + -3

7a = 24 + -3

Combine like terms: 24 + -3 = 21

7a = 21

Divide each side by '7'.

a = 3

Simplifying

a = 3
