Question

simplifique e resolva as equaçoes
A) 10x+4(3-2x) - 6=8
b) 3(5+3x)+5(-x-1=22
c) 2(9x-4)-7+(6-5x 3=18
Mim Ajudem Por Favor

Answer 1

a)10x+4(3-2x)-6=8
10x+12-8x-6=8
10x-8x=-8-12+6
2x=-14
x=-14/2
x=-7

b)3(5+3x)+5(-x-1)=22
15+9x-5x-5=22
4x=22-15-5
4x=2
x=2/4
x=1/2

c)2(9x-4)-7+(6-5x)3=18
18x-8-7+18-15x=18
18x-15x=18+8+7-18
3x=15
x=15/3
x=5
