Answer:
x=9 and y=3
Step-by-step explanation:
Let's solve your system by substitution.
−4x+6y=−18 and y=−2x+21
Rewrite equations:
y=−2x+21;−4x+6y=−18
Step: Solve y=−2x+21for y:
y=−2x+21
Step: Substitute−2x+21foryin−4x+6y=−18:
−4x+6y=−18
−4x+6(−2x+21)=−18
−16x+126=−18(Simplify both sides of the equation)
−16x+126+−126=−18+−126(Add -126 to both sides)
−16x=−144
−16x
−16
=
−144
−16
(Divide both sides by -16)
x=9
Step: Substitute9forxiny=−2x+21:
y=−2x+21
y=(−2)(9)+21
y=3(Simplify both sides of the equation)
Answer:
x=9 and y=3
Do me do me do me.............
The system of equations provides a unique solution(one solution) at (-0.6, 1.6).
<h2>Given to us,</h2>


<h3>Equation 2</h3>
As we already have the value of y from equation 1, substitute its value in equation 2,








<h3>Equation 1,</h3>

substitute the value of x in equation 1,

As we can see the system of equations provides a unique solution(one solution) at (-0.6, 1.6).
