5y-1 equals y plus 9

Answer 1

Simplifying

5y + -1 = y + 9

Reorder the terms:

-1 + 5y = y + 9

Reorder the terms:

-1 + 5y = 9 + y

Solving

-1 + 5y = 9 + y

Solving for variable 'y'.

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

Add '-1y' to each side of the equation.

-1 + 5y + -1y = 9 + y + -1y

Combine like terms: 5y + -1y = 4y

-1 + 4y = 9 + y + -1y

Combine like terms: y + -1y = 0

-1 + 4y = 9 + 0

-1 + 4y = 9

Add '1' to each side of the equation.

-1 + 1 + 4y = 9 + 1

Combine like terms: -1 + 1 = 0

0 + 4y = 9 + 1

4y = 9 + 1

Combine like terms: 9 + 1 = 10

4y = 10

Divide each side by '4'.

y = 2.5

Simplifying

y = 2.5
