Question

Find all values of c such that 5c - 4 = 7 - 4-c/3

Answer 1

5c - 4 = 7 - (4-c)/3
5c - 11 = - (4-c)/3
15c - 33 = -4 + c
14c = 29
    c = 29/14
    or
    c = 2 1/14

Answer 2

Hey there!

$5c - 4 = 7 - \dfrac{4 - c}{3} \\ 15c - 12 = 21 - 4 + c \\ 14c = 29 \\ c = 2 \dfrac{1}{14}$

Hope this helps. - M
