Question

4(x+3)=49-(x-3) 6x=-2+7x 2(y-5)+7=1

Answer 1

4(x+3)=49-(x-3)
4x+12-49+x-3=0
5x=40
x=8
-----------------------------------
6x=-2+7x 
-x=-2
x=2
--------------------------------
2(y-5)+7=1
2y-10+7-1=0
2y=4
y=2
==============================

Answer 2

4(х+3)=49-(х+3)
4х+12=49-х+3
4х+х=49-12+3
5х=40
х=40:5
х=8
Ответ:8.
6х= -2+7х
6х-7х=-2
-х=-2
х=2
Ответ:2
2(у-5)+7=1
2у-10+7=1
2у=10-7+1
2у=4
у=4:2
у=2
Ответ:2.
