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

mixer [17]

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

bearhunter [10]

Answer:

$106$

Step-by-step explanation:

Let's try guessing...

$45+45=90\\30+30+30=90\\10+20+30+30=90$

All the units place has to be 4, if it is higher than 4 then the answer will not be 90 (the sum of the four rounded numbers).

$14 + 24 + 34 + 34= 106$
