Answer: $6019
Step-by-step explanation:

and you'll get 6019.1 but it will only be right if you round to 6019
I took this assignment
26=7(g-9) + 1226
To find g, we expand the brackets first(multiplying every term in the bracket by the term outside it):
26=7g-63+1226
Add the terms on the right hand side:
26=7g+1163
Collect alike terms to left hand side:
26-1163=7g
-1137=7g
Divide equation by 7 to get g on its own:
g= -162.428 (3dp)
Hope this helps!
