3. 3(x-6)-10=2(x-5)-4
4. 5(x-2)-6(x-1)=3(2x-4).. ayúdenme x fa :)

Answer 1

x/2=2x-4
x=2x-4(2)
x=4x-8
x-4x=-8
3x=-8
x=8/3

2(x-5)-10=x-5
2x-10-10=x-5
2x-x=-5+10+10
x=15

3(x-6)-10=2(x-5)-4
3x-18-10=2x-10-4
3x-2x=-10-4+18+10
x=14

5(x-2)-6(x-1)=3(2x-4)
5x-10-6x+6=6x-12
5x-6x-6x=-12+10-6
-7x=-8
x=8/7
