Finish solving the system of equations 3x + 5y = −72 and 2x + 3y = –45 using the linear combination method.
Step 1: Create an equivalent system with opposite terms:
−2(3x + 5y = −72) → −6x − 10y = 144
3(2x + 3y = −45) → 6x + 9y = −135
Step 2: Add the equivalent system of equations to eliminate a variable: −y = 9
Step 3: Solve for the first unknown variable: y = −9
Step 4: Substitute the value of the first variable into one of the original equations: 2x + 3(−9) = −45
Step 5: Solve for the second unknown variable and write the solution as an ordered pair:
What is the solution to the system?
