is this correct ? check plsss...


given 17= 37 + 4f; f = 5


Answer: first to solve for variable f

by subtracting the right of the equal sign from both sides of the equations

solve: -4f each side of the equation 17 + -4f = 37 + 4f + -4f

combine like terms: 4f + -4f =0 so 17 + -4f = 37 + 0

17 + -4f = 37 then add - 17 to each side of the equation

17 + -17 + -4f = 37 + -17 to combine the like terms: 17 + -17=0

0 + -4f = 37 + -17

-4f = 37 + -17

COMBINE: 37 + -17 = 20

-4f = 20 divide each side by -4 so the answer is f= -5

I hope you will understand my answers. Thank you.
