Question

resolva as equaçoes abaixo:
x+5=AX+19
X+15-3X-4=7x+2-9x-9
2x-2=28-3x
2x+54+7x=3X+12
5X+12-2X-9+8X=7+4X+10+3X-2

Answer 1

x+5=AX+19
x-Ax=19-5
x-Ax=14
Esse A, no exercício está mal formulado

X+15-3X-4=7x+2-9x-9
x-3x-7x+9x=2-9-15+4
x= -18

2x-2=28-3x
2x+3x=28+2
5x=30
x=30/5
x=6


2x+54+7x=3X+12
2x+7x-3x=12-54
6x= -42
x= 42/6
x=7

5X+12-2X-9+8X=7+4X+10+3X-2
5x-2x+8x-4x-3x=7+10-2-12+9
13x-9x=26--14
6x=12
x=12/6
x= 2
boa sorte
