Question

if, y:10y = 4y + 180
then find y​

Answer 1

Answer:

$10y = 4y + 180 \\ 10y - 4y = 180 \\ 6y = 180 \\ y = 180 \div 6 \\ y = 30$

Answer 2

Answer:

y = 12.92857143

Step-by-step explanation:

Simplifying

10y + 4y + -1 = 180

Reorder the terms:

-1 + 10y + 4y = 180

Combine like terms: 10y + 4y = 14y

-1 + 14y = 180

Solving

-1 + 14y = 180

Solving for variable 'y'.

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

Add '1' to each side of the equation.

-1 + 1 + 14y = 180 + 1

Combine like terms: -1 + 1 = 0

0 + 14y = 180 + 1

14y = 180 + 1

Combine like terms: 180 + 1 = 181

14y = 181

Divide each side by '14'.

y = 12.92857143
