Step-by-step explanation:

Step 1: Define Systems

-3x + 4y = 64

x + 4y = 32

Step 2: Rewrite Systems

x + 4y = 32

[Subtract Property of Equality] Subtract 4y on both sides: x = 32 - 4y

Step 3: Redefine Systems

-3x + 4y = 64

x = 32 - 4y

Step 4: Solve for y

Substitution

Substitute in x: -3(32 - 4y) + 4y = 64Distribute -3: -96 + 12y + 4y = 64Combine like terms: 16y - 96 = 64[Addition Property of Equality] Add 96 on both sides: 16y = 160[Division Property of Equality] Divide 16 on both sides: y = 10

Step 5: Solve for x

Define equation: x + 4y = 32Substitute in y: x + 4(10) = 32Multiply: x + 40 = 32[Subtraction Property of Equality] Subtract 40 on both sides: x = -8
