Question

a) 8(x+1) - 4(x-3)-x=2(x+18) b)4x+12-3(x+4)=2(x+5) c) 5x+16-4(x+4)=2(x+9) d) 4(x+5)+3(x+3)=2(x+15)+4 e) 5(x+2)+4(x-3)=3(x+8)-14

Answer 1

a)8x+8-4x+12-x=2x+36
3x+8+12=2x+36
x=16
b)4x+12-3x-12=2x+10
2x=10
x=5
c)5x+16-4x+16=2x+18
2x=18
x=9
d)4x+20+3x+9=2x+30+4
7x+29=2x+34
5x=-29+34
5x=5x=1
e)5x+10+4x-12=3x+24-14
x-2=3x-10
-3x=12
-x=-4
