Question

I need help solving this problem. It tells me that I cant use a decimal. But for my answer I got a decimal. -9 + 2 ( 4g - 7 ) = 9.

Answer 1

18 = 2 (4g - 7)
9 = 4g - 7
16 = 4g
g = ...?

Answer 2

i also get a decimal, i tried to prove g=4 as per @jack1 but LHS does not = RHS

Answer 3

...?
why?

Answer 4

hi @jack1 isn't g = 4 ?

Answer 5

yep, but why doesnt ur LHS = RHS?

Answer 6

if i look at the original question shouldn't LHS = 9?

Answer 7

yeah...?

Answer 8

\[-9+2\left( 4\left( 4 \right) - 7 \right) = 9\]
\[-9 + 2\left( 16-7 \right)=9\]
\[-9 + 2 (9) = 9\]
\[-9 + 18 = 9\]
\[9 = 9\]
