Answer:
Step-by-step explanation:
Step 1:
Isolate x (1st Equation)
2x + 3y = 0
- 3y = -3y
2x = -3y
Step 2:
Divide both sides by 2
x = -3y/2
Step 3:
Replace the x from 8x with -3y/2 and Solve the equation
8(-3y/2) + 9y = 18
-12y + 9y = 18
-3y = 18
y = -6
Step 4:
Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0
2x - 18 = 0
+ 18 = +18
2x = 18
x = 9
Step 5:
Write your final answer.
(x, y) = (9, -6)
