Question

Solve this equation.
75 – 3.5y – 4y = 4y + 6

Answer 1

y=6

Explanation:

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

combine like terms)

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

75-7.5y=4y+6

add 4y to each side to combine the terms) 75+(-7.5y-4y)=6

75-11.5y=6

subtract 75 from each side to isolate the variable) -11.5y=-69

divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5

y=6
