Question

Solve 2/3 (c-18) = 7

Answer 1

do you mean (2/3) (c-18) = 7
or 2 / ( 3 (c-18) ) = 7?

Answer 2

In other words, is (c-18) a standalone term multiplied by 2/3, or is it in the denominator of 2/3?

Answer 3

c-18 stand alone

Answer 4

Assuming the first case, you would have

(2/3) (c-18) = 7
(2(c-18) ) / (3) = 7
(2c-36) / 3 = 7
2c-36 = 7 * 3
2c-36 = 21
2c = 21+36
2c = 57
c = 57 / 2
c = 28.5

Answer 5

c-18 = 7 x 3/2 = 21/2

c= 18 +21/2 = 28.5
