Question

a) 2(x-3)-(3x - 1 ) = 5

b) -(x+1) - 2 (1-x) = -4

c) 3(x-2) + 2(4-x) = 6

d) -2 (1 - x) + 3 (2x+1) = -7

e) (x+3) - (2x-1) = 1

f) -3(2-x) - 2(1-3x)=10

Answer 1

a) 2(x-3)-(3x - 1 ) = 5

2x-6-3x+1=5

x=-10

 

b) -(x+1) - 2 (1-x) = -4

-x-1-2+2x=-4

x=-1

 

c) 3(x-2) + 2(4-x) = 6

3x-6+8-2x=6

x=4

 

d) -2 (1 - x) + 3 (2x+1) = -7

-2+2x+6x+3=-7

8x=-8

x=-1

 

e) (x+3) - (2x-1) = 1

x+3-2x+1=1

x=3

 

f) -3(2-x) - 2(1-3x)=10 

-6+3x-2+6x=10

9x=18

x=2
