Question

1.-20m+13=-2m-5 2.-15m=m 3.-6y=6+6y 4.-2x+3=5x-4 5.3/4x+3=5+

Answer 1

1.-20m+13=-2m-5

-20m+2m=-5-13

-18m=-18

m=1

2.-15m=m

-15m-m=0

-16m=0

m=0

3.-6y=6+6y

-6y-6y=6

-12y=6

y=-1/2

4.-2x+3=5x-4

-2y-5y=-4-3

-7y=-7

y=1

5.3/4x+3=5+1/4x

3/4x-1/4x=5-3

2/4x=2

x=4

6.-2/3x=3/2

x=--9/4

7.0.3x-1.5=x+0.6

0.3x-x=0.6+1.5

-0.7x=2.1

x=-3

8.0.125x+2.75=-1.25x

125x+2750=-1250x

125x+1250x=-2750

1375x=-2750

x=-2

9.035x-1.5=-2.15x+3.5

0.35x+2.15x=3.5+1.5

2.5x=5

x=2
