Step: Solvex+y=14for x: x+y=14 x+y+−y=14+−y(Add -y to both sides) x=−y+14
Step: Substitute−y+14forxin42x+25y=486: 42x+25y=486 42(−y+14)+25y=486 −17y+588=486(Simplify both sides of the equation) −17y+588+−588=486+−588(Add -588 to both sides) −17y=−102 −17y −17 = −102 −17 (Divide both sides by -17) y=6
Step: Substitute6foryinx=−y+14: x=−y+14 x=−6+14 x=8(Simplify both sides of the equation)
