1) -(7-3)=8-8(2-y) 2) 1,24x+3,46=1,76x+6,58 3)4x-2(x+7)=2(3-x)

Question

1) -(7-3)=8-8(2-y)

2) 1,24x+3,46=1,76x+6,58

3)4x-2(x+7)=2(3-x)

Answer 1

2)1,24x+3,46=1,76x+6,58
1,24x-1,76x=6,58-3,46
-0,52x=3,12
x=3,12:(-0,52)
x=-6

Answer 2

4х-2(х+7)=2(3-х)
4х-2х+14=6-2х
2х+14=6-2х
2х+2х=6-14
4х=-8
х=-8÷4
х=-2


1.24х+3.46=1.76х+6.58
1.24х-1.76х=6.58-3.46
-0.52х=3.12
х=3.12÷(-0.52)
х=-6
