Answer 8

Thank you @PrincessHush

Answer 9

@That1BlackGuy
there are about 4 different ways to solve simultaneous equations.
Graphing as indicated by @PrincessHush is one of them but for this question the easiest to use would be elimination because the coefficients of one of the variables is already equal and opposite

Answer 10

add the 2 equations you will eliminate one variable. you now have one equation with one unknown. solve for this variable then substitute the value in either of the original to find the value of the other variable.

Answer 11

remember the solution to a simultaneous equation is the (x,y) set that satisfies both equations at the same time.
