8x+5y=14 -4X-5y=-2

Answer 1

x=3 and y=−2

Step-by-step explanation:

Solve8x+5y=14for x:

8x+5y=14

8x+5y+−5y=14+−5y(Add -5y to both sides)

8x=−5y+14

8x8=−5y+148(Divide both sides by 8)

x=−58y+74

Step: Substitute−58y+74forxin−4x−5y=−2:

−4x−5y=−2

−4(−58y+74)−5y=−2

−52y−7=−2(Simplify both sides of the equation)

−52y−7+7=−2+7(Add 7 to both sides)

−52y=5

−52y−52=5−52(Divide both sides by (-5)/2)

y=−2

Step: Substitute−2foryinx=−58y+74:

x=−58y+74

x=−58(−2)+74

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=−2
