Question

Me ajudem pomos eu preciso pra dia 14/11/17

Answer 1

A) 2x - 5 = x + 1
2x - x = 1 + 5
x = 6

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

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

D) 3x - 2 = 4x + 9
3x - 4x = 9 + 2
-x = 11 × (-1)
x = -11

E) 16x - 1 = 12x + 3
16x - 12x = 3 + 1
4x = 4
x = 4/4
x = 1

Answer 2

A) 2x-5=x+1
2x-x=5+1
X=6
B) 2x+3=x+4
2x-x=-3+4
X=1
C) 5x+7=4x+10
5x-4x=-7+10
X=3
D) 3x-2=4x+9
3x-4x=2+9
-x=11 (*-1)
X=-11
E) 16x-1=12x+3
16x-12x=1+3
4x=4
4/4
X=4
