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.

this looks one hundred percent correct to me and to check your answer you can plug in the answer you find to the first equation 


17=37+4f 
17=37+4(-5)
17=37-20
17=17 

great job!!
