Question

resolva as equações abaixo:
a) 5x+6x-16=3x+2x-4
b)4(x+10)-2(x-5)=0
c)3(2x+3)-4(x-1)=3
d)7(x-1)-2(x-5)=x-5
e)2(3-x)=3(x-4)+15
f)3(5-x)-3(1-2x)=42
g)5x-7/2=1/2+x
h)2x-1/3=x-x-1/5
i)x/4=3x-2/2=x-3/2
j)2(x-1)/3=3x+6/5

Answer 1

a) 5x + 6x - 3x - 2x = -4 + 16

6x = 12

b) 4x + 40 - 2x + 10 = 0

4x - 2x = -40 -10

2x = -50

x = -50

x = -25

c) 6x + 9 - 4x + 4 = 3

6x - 4x = 3 - 9 - 4

2x = -10

x = -10
