6m+5=2m-6
7(2p-3)=5(6p-1)
-(y+12)=9(-7-2y)
-(x+7)=5(-11-5x)
7(2x+4)=28

Do mathematical operations,then put unknown values on left side of equation,nubers on right side.

For example:

-(x+40)=10(3x-4)
-x-40=30x-40
-x-30x=-40+40
-29x=0
x=0

-11x+13=-42
-11x=-42-13
-11x=55 Divide with -11
x= -5

9x+2=15x-10
9x-15x= -10-2
-6x= -12 Divide with -6
x=(-12)/(-6)=2

2(4-7y)=3(3-2y)
8-14y=9-6y
-14y+6y=9-8
-8y=1 Divide with -8
y= -1/8
