Question

Which is a solution for 7 (x + 2) = 35? A. -2 B. 7/33 C. 3 D. 5 E. 26

Answer 1

7(x+2)=35
The seven is carried to the variable and multiples with 2

7x+14=35
-14 -14

14 is subtracted with 35 since they’re alike. 14 couldn’t be subtracted from 7x since it’s not a like term.

7x = 21
—- ——
7x 7x

7x is divided on both side in order to isolate the variable.

x=3

21/7 is 3


I hope this helped

Answer 2

7(x+2) = 35

Use the distributive property:

7x + 14 = 35

Subtract 14 from each side:

7x = 21

Divide both sides by 7:

x = 21 / 7

X = 3

The answer is C. 3
