Question

In the equation, which is true about the value of x?

3x + 7(x + 1) = 2(6x + 5) − 2x
A) x = 7, x = 10
B) no solution
C) single solution
D) infinitely many solutions

Answer 1

Answer: no solution

Explanation:

3x + 7(x + 1) = 2(6x + 5) − 2x

3x + 7*x + 7*1 = 2*6x + 2*5 - 2x

3x + 7x + 7 = 12x + 10 - 2x

3x + 7x - 12x + 2x = 10 - 7

(3+7-12+2)*x = 3

0*x = 3

no solution
