x=-2/3x=23

Explanation:

Solve:

15x-2=30x+815x2=30x+8

Subtract 15x15x from both sides of the equation.

15x-15x-2=30x+8-15x15x15x2=30x+815x

Simplify.

0-2=15x+802=15x+8

-2=15x+82=15x+8

Subtract 88 from both sides.

-2-8=15x28=15x

Simplify.

-10=15x10=15x

Divide both sides by 1515.

(-10)/15=(cancel(15)^1x)/cancel(15)^1

Simplify.

-10/15=x

Reduce the fraction by dividing the numerator and denominator by 5.

-(10-:5)/(15-:5)=x

-2/3=x

Switch sides.

x=-2/3
