Sagot :
Answer:
Step-by-step explanation:
Write the question in an equation form;
-x+y=2——-equation (1)
x+y=3——-equation(2)
Make y the subject in equation(1)
y=2+x
Substitute y=2+x into equation(2)
x+2+x=3
Group like terms
x+x=3-2
2x=1
Divide both sides by the coefficient of x
2x/2=1/2
x=1/2
Substitute x=1/2 into equation (2)
1/2+y=3
Group like terms
y=3-1/2
y= 6/2 -1/2
y= 5/2
Hence; the values of x and y are 1/2 and 5/2 respectively.
