Answer:
x= -7, y= 12
Step-by-step explanation:
To find the value of x and y, first label the 2 equations.
2x +y= -2 -----(1)
x +y= 5 -----(2)
(1) -(2):
2x +y -(x +y)= -2 -5
2x +y -x -y= -7 <em>(</em><em>expand</em><em> </em><em>bracket</em><em>)</em>
x= -7
subst. x= -7 into (2):
-7 +y= 5
y= 5 +7 <em>(</em><em>+</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
y= 12
