Hello!
2(x + 9) = 4(x + 7) + 2
Distribute the 2
2x + 18 = 4(x + 7) + 2
Distribute the 4
2x + 18 = 4x + 28 + 2
Combine like terms
2x + 18 = 4x + 30
Subtract 18 from both sides
2x = 4x + 12
Subtract 4x from both sides
-2x = 12
Divide both sides by -2
x = -6
Where she did something different than me is her mistake
Hope this helps!

5(p+6)=8p
5p+30=8p
8p-5p=30
3p=30
30/3
p= 10 is your answer

3(g+7)=2(10+g)
3g-21=20+2g
3g-2g
g-21=20
20+21
g=41 is your answer

3/7 w -11= -4/7 w
3/7w=-4/7 + 11
3/7 w = 73/7 x 7
3w = 511/7
3w= 73
w= 73/7 is your answer
3 and a half cookies! that should be the answer!
