Question

a)x + 3 = 2x + 1 b) 4x + 2 = 5x-1 c) 2 (x-1) = 4x – 3 d) -5(x+3) +8 (x+2) =10 e) 2x/3+2=x/3+5 f) ) x/2+3/8=x/4+1

Answer 1

A) x+3=2x+1 B)4x+2=5x-1

3-1=2x-x 2+1=5x-4x

2=x 3=x

C) 2(x-1)=4x-3

2x-2=4x-3

-2-3=4x-2x

-5=2x

-5÷2=x

-2;5=x

D) -5(x+3)+8(x+2)=10

-5x-15+8x+16=10

-5x+8x=10-15+16

3x=21

x=21÷3

x=7

E) 2x/3+2=x/3+5

2x (3)+2=x (3)+5

6x+2=3x+5

6x-3x=5-2

3x=3

x=3÷3

x=1
