Question

75 – 3.5y – 4y = 4y + 6

what is y=

Answer 1

Answer:

-3.5y-4y-4y=6-75

-11.5y=-69

y =69/11.5

y=6

Answer 2

Answer:

y=6

Step-by-step explanation:

Simplifying

75 + -3.5y + -4y = 4y + 6

Combine like terms: -3.5y + -4y = -7.5y

75 + -7.5y = 4y + 6

Reorder the terms:

75 + -7.5y = 6 + 4y

Solving

75 + -7.5y = 6 + 4y

Solving for variable 'y'.

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

Add '-4y' to each side of the equation.

75 + -7.5y + -4y = 6 + 4y + -4y

Combine like terms: -7.5y + -4y = -11.5y

75 + -11.5y = 6 + 4y + -4y

Combine like terms: 4y + -4y = 0

75 + -11.5y = 6 + 0

75 + -11.5y = 6

Add '-75' to each side of the equation.

75 + -75 + -11.5y = 6 + -75

Combine like terms: 75 + -75 = 0

0 + -11.5y = 6 + -75

-11.5y = 6 + -75

Combine like terms: 6 + -75 = -69

-11.5y = -69

Divide each side by '-11.5'.= 6

Simplifying

y = 6
