Solving Equations With Variables On Both Sides

Solve Equations with Variables on both sides I

100

7a+10=2a

a=-2

200

3-10b=2b-9

b=1

300

4n+13=n-8

n=-7

400

6x+10=1x

x=-2

Solve Equations with Variables on both sides II

100

11x=24+8x

x=8

200

2z-31=-9z+24

z=5

300

9-2y=8y-6

y=1.5

400

7a-5=2a

a=1

Solve Equations with Variables on both sides III

100

3a-1=2a

a=1

200

5n+9=2n

n=-3

300

x+5=4x+26

x=7

400

x+5=4x+26

what is x = 7
