Question

7(25-q) - 2q = (3q-25) ​

Answer 1

Step-by-step explanation:

175 - 7q -2q = 3q -25

175 + 25 = 3q + 2q + 7q

200 = 12q

12q = 200

$q = \frac{200}{12}$

q = 16.666....7

Answer 2

Answer:

$7(25 - x) - 2x = 3x - 25 \\ 175 - 7x - 2x = 3x - 25 \\ 175 + 25 = 3x + 9x \\ 200 = 12x \\ \frac{100}{6} = \frac{50}{3} = x$

let q be x
