Set this up as follows...
12x - 10 = 7x + 20
solve for x
X is 6
sub VW=7X with 7•6
VW=42
check by subbing also for UW
72 - 10 is 62
uV plus VW equals 62. it checks out.

Step-by-step explanation:
Answer: g(1) is 1.
Step-by-step explanation:
If we are solving for g of 1 then the first equation can't be used to solve for g of 1 because it only works in x is equal to -2.
The same way the second function will not work because x has to equal to -1.
But in the last function which is written as a polynomial it will work for this situation because x is not equal to -2 or -1 so apart from those numbers every number will work the same way 1 will work.
So plot 1 into the function and solve for it .
g(1) = 1^3 - 1^2 + 1
g(1)= 1 - 1 + 1
g(1)= 1
