To solve the equation -x - 3=.2 - 2x-15, you
could graph of the following system.
y = -x-3
y = 22 - 2x - 15
Use the graph of this system to identify all
solutions of -x-3 = 22 - 2x - 15.
-7
0.
DONE

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
