Question

resolva as equações em U=Q

A) 5x+2=2x-4
B) 2x+1=x+11
C) 4x+9=3x+5
D) 5x-7-2x-2=0

Answer 1

5x+2=2x-4
5x-2x=-4-2
3x=-6
x=-6/3
x=-2

2x+1=x+11
2x-x=11-1
x=10

4x+9=3x+5
4x-3x=5-9
x=-4

5x-7-2x-2=0
5x-2x=7+2
3x=9
x=9/3
x=3

Answer 2

Oi,

Resolução


A) 5x+2=2x-4
5x - 2x = - 4 - 2
3x = - 6
x = - 6/3
x = - 2


B) 2x+1=x+11
2x - x = 11 - 1
x = 10


C) 4x+9=3x+5
4x - 3x = 5 - 9
x = - 4


D) 5x-7-2x-2=0
5x - 2x = 7 + 2
3x = 9
x = 9/3
x = 3

Espero ter ajudado e bons estudos!
