Question

Simplify. 6(y+13)+21y

Answer 1

Simplifying 6y + 1 = 21y + 13

Reorder the terms: 1 + 6y = 21y + 13
Reorder the terms: 1 + 6y = 13 + 21y

Solving 1 + 6y = 13 + 21y

Solving for variable 'y'.

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

Add '-21y' to each side of the equation. 1 + 6y + -21y = 13 + 21y + -21y

Combine like terms: 6y + -21y = -15y 1 + -15y = 13 + 21y + -21y

Combine like terms: 21y + -21y = 0 1 + -15y = 13 + 0 1 + -15y = 13

Add '-1' to each side of the equation. 1 + -1 + -15y = 13 + -1

Combine like terms: 1 + -1 = 0 0 + -15y = 13 + -1 -15y = 13 + -1
Combine like terms: 13 + -1 = 12 -15y = 12
Divide each side by '-15'. y = -0.8
Simplifying y = -0.8
