Answer: 1. x=4
2. x=12
3. x=-1
Step-by-step explanation:
1. 2(3x-5)=-4x+30
6x-10=-4x+30
6x+4x-10=-4x+4x+30
10x-10=30
10x-10+10=30+10
10x=40
10x/10=40/10
x=4
2. 5x-6-3x=18
5x-3x-6=18
2x-6=18
2x-6+6=18+6
2x=24
2x/2=24/2
x=12
3. -11-5x=6(5x+4)
-11-5x=30x+24
-11-5x+5x=30x+5x+24
-11=35x+24
-11-24=35x+24-24
-35=-35x
x=-1
