Question

n) 2x+3=x+4
o) 5x+7=4x+10
p) 4x-10=2x+2
q) 4x-7=8x-2

Answer 1

N) 2x+3=x+4
2x -x = 4 -3
x= 1

O) 5x+7=4x+10
5x -4x = 10 -7
x= 3

P) 4x-10=2x+2
4x - 2x= 2 +10
2x = 12
x= 12/2
x= 6

Q) 4x-7=8x-2
4x - 8x= -2 +7
-4x = 5 . (-1)
4x = -5
x= -5/4
x= -1,25

Bons estudos!

Answer 2

N) 2x + 3 = x + 4
2x - x = 4 - 3
x = 1
o) 5x + 7 = 4x + 10
5x - 4x = 10 - 7
x = 3
p) 4x - 10 = 2x + 2
4x - 2x = 2 + 10
2x = 12
x = 12/2
x = 6
q) 4x - 7 = 8x - 2
4x - 8x = - 2 + 7
- 4x = + 5(multiplicando por - 1)
4x = - 5
x = - 5/4
