Question

1. 3р+5=8р-15
2. 0.7x-1.82=0.8x+3.46
3. 0.18x-3.54=0.19x-2.89
4. 2-3(x+2)=5-2x
5. 4x-5.5=5x-3(2x-1.5)
6. 4(3-2x)+24=2(3++2x)
7. 0.9(4x-2)=0.5(3x-4)+4.4

Answer 1

-5р=-20
р=4

0.1х=5.28
х=52.8

0.01х=0.65
х=6.5

Answer 2

1) 3р +5=8р-15
3р-8р=-15-5
р=4
2) 0.7х-0.8х=3.46+1.82
-0.1х = 5.28
х= - 52.8
3) 0.18х-0.19х=-2.89+3.54
-0.01х=0.65
х =-65
4) 2-3х-6=5-2х
-4-3х=5-2х
-3х+2х=5+4
-х=9
х= - 9
