Answer 2

Simplifying

10y + -7 = 5y + 3

Reorder the terms:

-7 + 10y = 5y + 3

Reorder the terms:

-7 + 10y = 3 + 5y

Solving

-7 + 10y = 3 + 5y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-5y' to each side of the equation.

-7 + 10y + -5y = 3 + 5y + -5y

Combine like terms: 10y + -5y = 5y

-7 + 5y = 3 + 5y + -5y

Combine like terms: 5y + -5y = 0

-7 + 5y = 3 + 0

-7 + 5y = 3

Add '7' to each side of the equation.

-7 + 7 + 5y = 3 + 7

Combine like terms: -7 + 7 = 0

0 + 5y = 3 + 7

5y = 3 + 7

Combine like terms: 3 + 7 = 10

5y = 10

Divide each side by '5'.

y = 2

Simplifying

y = 2
