: Question #33 says: use the substitution method to solve the linear system these are the equations 7g+h=-2 and g-2h=9. i reworte the second equation to make it look like this g=2h+9 then i plugged them in and got this 7(2h+9)+h=-2 turning out in 15h+63=-2 then i subtracted the 63 an got 15h=-65 then i divided the -65 by 15 to isolate the variable and got -4 33/100 but in the back of the book it says the y is 4 1/3 what did i do wrong? help please!
