Question

a) 2x + 7x - 10 = 4x + 3 - 2x 

b)3* (x+1) = 8

c)4* (x-6) = -3

d) 2* (3 - x) =  -4* (x-1)
 
e) -1* (x+4) = 3* (x+5

f)2(x-1)/3 + x+2 = 1

g)2x - /10 - 1-x/5 = 0
 
Me ajudem pfv 

Answer 1

a)
2x+7x-10=4x+3-2x
9x-10=2x+3
9x-2x=10+3
7x=13
x=13/7

b)
3*(x+1)=8
3x+3=8
3x=8-3
3x=5
x=5/3

c)
4*(x-6)=-3
4x-24=-3
4x=24-3
4x=21
x=21/4

d)
2*(3-x)=-4*(x-1)
6-2x=-4x+4
6-4=2x-4x
2=-2x
2x=-2
x=-2/2
x=-1

e)
-1*(x+4)=3*(x+5)
-x-4=3x+15
-15-4=3x+x
-19=4x
4x=-19
x=-19/4

f)
[2(x-1)/3]+x+2=1
(2x-2)/3+x+2=1
2x-2+3x+6=3
5x+4=3
5x=3-4
5x=-1
x=-1/5

g)
(2x/-10)-1-x/5=0
5(2x)+50+10x=0
10x+50+10x=0
20x+50=0
20x=-50
x=-50/20
x=-5/2
