Question

Simplify the given equation.

6 - (3x + 10) + 4(2 - x) = 15

Answer 1

Answer: 4 - 7x = 15

Note:

To complete this problem without actually solving for x, you have to stop midway and there is your answer.

Explanation:

-(3x+10) = -3x-10

4(2-x) = 8-4x

(6-3x-10+8-4x)

6-10+8=4

Now, put the x's together, giving you 7x.

Your final answer will be

4-7x=15

Answer 2

6-(3x+10)+4 (2-x)=15
6-3x-10+8-4x=15
6-10+8-15=4x+3x
7x=-11
x=-11/7
