the equation where x = 12 will not be a solution is x + 4 = 10 (3rd option)
Explanation:Given:
4 expressions with respect o x
To find:
the equation where x = 12 will not be a solution
To determine this, we will substitute x with 12 in each of the expressions. Then compare the right side with the left side of the equation
a) 5 + 4x = 53
when x = 12
5 + 4(12) = 53
5 + 48 = 53
53 = 53 (left side = right side)
b) 9x - 7 = 101
9(12) - 7 = 101
108 - 7 = 101
101 = 101 (left side = right side)
c) x + 4 = 10
12 + 4 = 10
16 = 10 (left side not equal to right side)
d) 96 ÷ x = 8
96 ÷ 12 = 8
8 = 8 (left side = right side)
The only option has a different answer on both left and right. As a result, the equation where x = 12 will not be a solution is x + 4 = 10 (3rd option)
