Question

Raiz da equação 3(a-4x)+7(2x-a)-5(3x+2a)+a=0

Answer 1

3(a - 4x) + 7(2x - a) - 5(3x + 2a) + a = 0
3a - 12x + 14x - 7a - 15x - 10a + a = 0
3a - 7a - 10a + a - 12x + 14x - 15x = 0
-13a - 13x = 0
-13(a - x) = 0

BONS ESTUDOS!

Answer 2

3(a-4x)+7(2x-a)-5(3x+2a)+a=0
3a-12x+14x-7a-15x-10a+a=0
-13a-13x=0
-13x=13a
x=-a
