To solve this you would have to do 10x/10=20/10. 20/10=2. Therefore, x=2.

U divide 10 both sides so it will be 10x/10=20/10
then x=2

8+5y=(8y-6)-7 how to work it out
zvonat [6]

the solution is y = 7

Step-by-step explanation:

Given equation is

8+5y=(8y-6)-7

The equation has to be solved for y

So,

Opening brackets first

8+5y=8y-6-7\\8+5y=8y-13

Subtracting 8 from both sides

8+5y-8=8y-13-8\\5y=8y-21

subtracting 8y from both sides

5y-8y = 8y-21-8y\\-3y=-21y

Dividing both sides by -3

\frac{-3y}{-3} = \frac{-21}{-3}\\y = 7

so,

the solution is y = 7
