Can someone help me solve this ?

1 answer:

6 0

$5x {}^{2} + 6x - 3 + 4x {}^{2} - 8x + 2 =$
$= 9x {}^{2} - 2x - 1$
In the original expression there are 6 terms in the simplyfied one there are only 3

In the simplified expression coefficient of x is (-2)

Use elimination to solve each system of equations 2x-y=-1 3x-2y=1

mixer [17]

$2x-y=-1 \ \ \ |\times (-2) \\
3x-2y=1 \\ \\
-4x+2y=2 \\
\underline{3x-2y=1 \ \ \ \ } \\
-4x+3x=2+1 \\
-x=3 \ \ \ |\times (-1) \\
x=-3 \\ \\
2x-y=-1 \\
2 \times (-3)-y=-1 \\
-6-y=-1 \ \ \ |+6 \\
-y=5 \ \ \ |\times (-1) \\
y=-5 \\ \\
\boxed{(x,y)=(-3,-5)}$
