Question

Which equation is false for x = 6?

A) 2x − 8 = 5
B) 3x + 7 = 25
C) 4x + 12 = 36
D) 6x − 6 = 30

Answer 1

choice A. Since 12 -8 = 4 not 5

Explanation:

if we plug in x =6 for 2x -8 = 5

2*6 - 8 = 12 - 8 = 4 not 5

Try B. 3*6 + 7 = 18 + 7 = 25 = 25 true

Try C. 4*6 + 12 = 24 + 12 = 36 = 36 true

Try D. 6*6 - 6 = 36 - 6 = 30 = 30 True
