Question

x+1=10

2x- 4 = 3 - 6x

2x + 10 = 20

2(x + 1)= x + 10

Answer 1

a) x=10-1                    
x=9
b) 2x+ 6x = 3+4
8x=7
x=7/8
c) 2x = 20-10
2x=10
x=10/2
x=5
d) 2x +x = x+10
3x-x=10
2x=10
x=5

Answer 2

x+1=10
x=10-1
x=9

2x-4=3-6x
2x+6x=3+4
8x=7
x=7/8
x=1,142857142857143

2x+10=20
2x=20-10
2x=10
x=10/2
x=5

2(x+1)=x+10
2x+2=x+10
2x-x=10-2
x=8
