Question

Qual o valor da incógnita "x" das expressões?
5x + 4 - 2x = 26 - 3x

-10 + 4 - 2x = -4x - 7

Answer 1

5x + 4 - 2x = 26 - 3x

6x=22

X=22/6=11/3

X=3,66

-10 + 4 - 2x = -4x - 7

2x=1

X=1/2

X=0,5

Answer 2

5x+4-2x=26-3x

5x-2x+3x=26-4

6x=22

x=22/6

-10+4-2x=-4x-7

-2x+4x=-7+10-4

2x=-1

x=-1/2
