Question

Which ordered pair is a solution of the equation?

3x+3y=-x+5y3x+3y=−x+5y

​

Answer 1

Answer:

Step 1: Equation 1, Solved for Y:

y = 3x + 5 [Divided by 4]

Step 2:

Equation 2, Substituted Y1: 4x + 2(3x + 5) = 20

Equation 2, Substituted Y1: 4x + 6x + 10 = 20

Equation 2, Substituted Y1: 10x + 10 = 20

Equation 2, Substituted Y1: 10x + 10 - 10 = 20 - 10

Equation 2, Substituted Y1: 10x = 10

Equation 2, Substituted Y1: x = 1

Step 3:

4y = 12(1) + 20

4y = 32

y = 8

Step 4: Test the Solutions [x = 1, y = 8]

Equation 1: 4(8) =? 12(1) + 20

32 =? 20 + 12

32 = 32

Equation 2: 4(1) + 2(8) =? 20

4(1) + 2(8) =? 20

4 + 16 =? 20
