Answer:
x=5, y=8
Step-by-step explanation:
Since both equations equal y, we can set them equal
y = x + 3
y = 2x - 2
x+3 = 2x-2
Subtract x from each side
x-x+3 = 2x-x-2
3 = x-2
Add 2 to each side
3+2= x-2+2
5 =x
Now we need to find y
y =x+3
y=5+3
y=8
Answer:
x = 5
y = 8
Step-by-step explanation:
to solve the linear system of equation , we would say that let
y = x + 3................................. equation 1
y = 2x - 2 ............................................. equation 2
substitute for equation 1 into equation 2
we have
x + 3 = 2x -2
collect the like terms
x + 3 + 2 = 2x
x + 5 = 2x
5 = 2x -x
5 = x
x = 5
substitute for the value of x = 5 in equation 2
y = 2x - 2 ............................................. equation 2
y = 2(5) - 2
y = 10 - 2
y = 8
Therefore the value of x and y in the linear equation is 5 and 8 respectively
