If d-3f+g=17, determine the value of the expression 2(d+2)-(4f-3)+(f+g-d).

4 answers

2(d+2)-(4f-3)+(f+g-d)
= 2d + 4 - 4f + 3 + f+g-d
= d - 3f + g + 7
= 17+7 = 24
how did you get the 17+7=24?
did you follow it up to
= d - 3f + g + 7
= (d - 3f + g) + 7 , but you told me d - 3f + g = 17
= 17+7
= 24
ohhhh ok I see. I feel dumb. Thank you for showing me how to solve this problem!
