Question

which equation has the solution x = 4? answer 8x + 8 = 40 8x + 6 = 102 5x - 4 = 37 6x - 6 = -18

Explanation:

Step1: Check the first - equation

Substitute $x = 4$ into $8x+8$. We get $8\times4 + 8=32 + 8=40$.

Step2: Check the second - equation

Substitute $x = 4$ into $8x + 6$. We get $8\times4+6=32 + 6=38
eq102$.

Step3: Check the third - equation

Substitute $x = 4$ into $5x-4$. We get $5\times4-4=20 - 4=16
eq37$.

Step4: Check the fourth - equation

Substitute $x = 4$ into $6x-6$. We get $6\times4-6=24 - 6=18
eq - 18$.

Answer:

$8x + 8 = 40$
