Please help!! I'll give 50 points Solve the system of equations.
2x + 9y = 6

-7x - 8y = -21

y=0 and x=3

Step 1: Solve for x in 2x+9y=6.

(Subtract 9y from both sides)

( Divide both sides by 2)

Step 2: Replace x with 3-4.5y

Step 3: Solve for y

(By looking at this, we can determine that y=0)

Step 4: Replace y with 0

(Divide both sides 2)

Therefore, y=0 and x=3

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
