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

Question

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

Answer 1

2(x-3)-5(x-7)=5-(x+6)
2x-6-5x+35=5-x-6
2x-5x+x=5-6+6-35
-2x=-30
x=-30:(-2)
x=15

2(2x-3)-3(7-5x)=4+(2-x)
4x-6-21+15x=4+2-x
4x+15x+x=4+2+6+21
20x=33
x=33/20
c=1.65
