Question

3(×+3)+2(2×-4)=12(2×-7)​

Answer 1

Explicación paso a paso:

$3(x+3)+2(2x-4)=12(2x-7) \\ 3x + 9 + 4x - 8 = 24x - 84 \\ 7x + 1 = 24x - 84 \\ 1 + 84 = 24x - 7x \\ 85 = 17x \\ 85 \div 17 = x \\ 5 = x$

Comprobación

$3(x+3)+2(2x-4)=12(2x-7) \\ 3(5+3)+2(2(5)-4)=12(2(5)-7) \\ 3(8) + 2(10 - 4) = 12(10 - 7) \\ 3(8) + 2(6) = 12(3) \\ 24 + 12 = 36 \\ 36 = 36$
