Answer:
x=−1 and y=5
Step-by-step explanation:
rewrite equations:
−6x+2y=16;−4x+y=9
Solve −4x+y=9for y:
−4x+y=9
−4x+y+4x=9+4x(Add 4x to both sides)
y=4x+9
Substitute 4x+9 for y in−6x+2y=16:
−6x+2y=16
−6x+2(4x+9)=16
2x+18=16 (Simplify both sides of the equation)
2x+18+−18=16+−18 (Add -18 to both sides)
2x=−2
2x/2=-2/2
x=−1
Substitute−1 for x in y=4x+9:
y=4x+9
y=(4)(−1)+9
y=5 (Simplify both sides of the equation)
and theres your answer
