\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3,
right parenthesis a solution of the system?
1 answer:
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation
