Question

11x-16=5x-4
2x-=17-2x=+1
3x-6=2x-4
7x-28=2x-3
3x-6=12-4x

Answer 1

a) 11x+16=5x-4
11x-5=-4+16
-6x=-12
x=-12/-6
x=2

b) 2x=17-2x=+1
2x+2x=17-1
4x=16
x=16/4
x=4

c) 3x-6=2x-4
3x-2x=-4+6
-1x=10
x=o.1

d) 7x-28=2x-3
7x-2x=-3+28
5x=31
x=31/5
x=6.2

e) 3x-6=12-4x
3x+4x=12+6
7x=18
x=18/7
x=2.571...
