Question

For which equation would x = 12 not be a solution?

5 + 4x = 53
9x - 7 = 101
x + 4 = 10
96 ÷ x = 8

Answer 1

Put the value of x to the equation.

$5+4x=53\\L=5+4(12)=5+48=53;\qquad R=53;\qquad L=R\\\\9x-7=101\\L=9(12)-7=108-7=101;\qquad R=101;\qquad L=R\\\\x+4=10\\L=12+4=16;\qquad R=10;\qquad L\neq R\\\\96\div x=8\\L=96:12=8;\qquad R=8;\qquad L=R$

Answer: x + 4 = 10
