Answer:
(-38,18)
Step-by-step explanation:
Step: Solvex+3y=16for x:
x+3y+−3y=16+−3y(Add -3y to both sides)
x=−3y+16
Step: Substitute−3y+16forxin2x+5y=14:
2x+5y=14
2(−3y+16)+5y=14
−y+32=14(Simplify both sides of the equation)
−y+32+−32=14+−32(Add -32 to both sides)
−y=−18 Divide both sides by -1
[tex]\frac{-y}{-1} =\frac{-18}{-1}[/tex]
y=18
Step: Substitute18foryinx=−3y+16:
x=−3y+16
x=(−3)(18)+16
x=−38
