Answer:
x = 3+1/2 y -----Equation-1
-2x-y = 2 -------Equation-1
Multiplying equation 1 by 2 we get
2x = 2*(3+1/2y)
2x = 6+y
y = 2x-6
substituting the value of of y in equation2
-2x - (2x-6) = 2
-2x -2x +6 = 2
-4x = 2-6
-4x = -4
x = -4/-4 = 1
y = 2x-6 = 2-6 = -4
x = 1
y = -4
Step-by-step explanation:
Answer:
x=0.75 and Y=-4.5
Step-by-step explanation:
let x=3+1/2y.....(1)
-2x-y=3.......(2)
substitute (1) into (2)
-2(3+1/2y)-y=3
-6-y-y=3
-2y=9
y=-9/2
put y=-9/2 into (1)
x=3+(1/2)(-9/2)
x=-4.5
