Coordinates (x, y)Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4y + x = -17

-2y + 2x = 16

Step 2: Rewrite Systems

-2y + 2x = 16

[Multiplication Property of Equality] Multiply 2 to both sides: 2(-2y + 2x) = 32[Distributive Property] Distribute 2: -4y + 4x = 32

Step 3: Redefine Systems

4y + x = -17

-4y + 4x = 32

Step 4: Solve for x

Elimination

Combine equations: 5x = 15[Division Property of Equality] Divide 5 on both sides: x = 3

Step 5: Solve for y

Substitute in x [Original Equation]: 4y + 3 = -17[Subtraction Property of Equality] Subtract 3 on both sides: 4y = -20[Division Property of Equality] Divide 4 on both sides: y = -5
