Question 1076522

Solve the system of linear equations by elimination. Check your solution. 
-2x - 5y = -8
-2x + y = 16
<pre>- 2x - 5y = - 8 -------- eq (i)
- 2x +  y =  16 -------- eq (ii)
       6y = 24 ------ Subtract eq (i) from eq (ii)
{{{highlight_green(matrix(1,5, y, "=", 24/6, "=", 4))}}}
Substitute value for y into any of the 2 original equations to get the value of x.
Do a check, as instructed.
