I will solve your equations by substitution. 12y = 4; x - 5y = 18

Step: Solve 12y = 4 for y: 12y / 12 = 4/12 (Divide both sides by 12) y = 13 Step: Substitute 1/3 for y in x - 5y = 18:

x - 5y = 18

x - 5 (1/3) = 18

x + - 5 / 3 = 18 (Simplify both sides of the equation)

x + - 5 / 3 + 5/3 = 18 + 5/3 (Add 5/3 to both sides)

x = 59/3

Answer: x = 59/3 and y = 1 / 3
