Question

d) 3+2(x-1)=17
e) 2x+3x=20
f) 8x+5-4x=41
g) 7+2x+6x=63
h) 2(x+5)=18
i) 3(x+2)-2x=10
j) 5(x+3)+s(x+3)=56

Answer 1

d) 2(x-1)=17-3
2(x-1)=14
x-1=14/2
x-1=7
x=7+1
x=8

e)5x=20
x=20/5
x=4

f)8x-4x=41-5
4x=36
x=36/4
x=9

g)2x+6x=63-7
8x=56
x=56/8
x=7

h)2x+10=18
2x=18-10
2x=8
x=8/2
x=4

i)3x+6-2x=10
x+6=10
x=10-6
x=4
