Question 33405
x-2y=3 and y=-x-1.5 

you are asked to find the solution when x = -3,0 and 2
so lets take first case of x = -3
simply substitute the value of x in the equations 

x - 2y = 3
-3 - 2y = 3
2y = -6
y = -3
so when x = -3 y = -3 (in the case of first equation)



y = -x - 1.5
y = -(-3)-1.5 
y = 3- 1.5 = 1.5

so when x = -3 , y = -1.5 (in the case of second equation)

So by following the same procedure try to find the solutions by substituting the given values of x in each equation
