Question

Solve and check 3x+2(x+2)=20-(2x-5)

Answer 1

hey mate
here is your answer
$3x + 2(x + 2) = 20 - (2x - 5) \\ 3x + 2x + 4 = 20 - 2x + 5 \\ 5x + 4 = 25 - 2x \\ 7x = 21 \\ x = 3$
checking
$3 \times 3 + 2(3 + 2) = 20 - (2 \times 3 - 5) \\ 9 + 6 + 4 = 20 - (6 - 5) \\ 19 = 20 - 1 \\ 19 = 19$
hope it helps
