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

A. x = 6; 7(6) = 35, 35 = 35
B. x = –5; 7(–5) = 35, –35 = –35
C. x = 245; 7(35) = 245, 245 = 245
D. x = 5; 7(5) = 35, 35 = 35

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

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

[tex]\frac{7x}{7} =\frac{35}{7}[/tex]

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
