Question

Find the solution of 7x = 35, and verify your solution using substitution.

Answer 1

Answer : option D

Find the solution of 7x = 35

To solve for x , we need to get x alone

so we divide by 7 on both sides

$\frac{7x}{7} =\frac{35}{7}$

So x= 5

To verify the solution we plug in 5 for x in the given equation 7x= 35

x=5

We have, 7x= 35

7(5)= 35

35= 35

So verified

Answer 2

The answer would be d because 5x7 would equal 35!
