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

Step-by-step explanation:

Step 1: Define Systems

y = 4x + 2

6x + 2y = 8

Step 2: Solve for x

Substitution

Substitute in y: 6x + 2(4x + 2) = 8Factor GCF: 2[3x + (4x + 2)] = 8[Division Property of Equality] Divide 2 on both sides: 3x + 4x + 2 = 4Combine like terms [Addition]: 7x + 2 = 4[Subtraction Property of Equality] Subtract 2 on both sides: 7x = 2[Division Property of Equality] Divide 7 on both sides: x = 2/7

Step 3: Solve for y

Substitute in x [Original equation]: y = 4(2/7) + 2Multiply: y = 8/7 + 2Add: y = 22/7

Step 4: Evaluate

Substitute in variables: 2/7 + 22/7Add: 24/7
