Question

Solve 15 (x-1)+4 (x+3) =2 (7x+)​

Answer 1

Answer:

15(x-1) +4(x+3) = 2(7x+1)

15x-15 +4x +12 =14x +2

19x -3 =12x+2

7x=5

x=5/7

Answer 2

Answer:

$15(x - 1) + 4(x + 3) = 2(7x + 1) \\ \\ 15x - 15 + 4x + 12 = 14x + 7\\ \\ 19x - 3 = 14x \\ \\ 19x - 14x = 3 + 7 \\ \\ 5x = 10 \\ \\ x = \frac{10}{5}$

x = 2
