Question

Solve the linear system using subsitiution.
Please show steps
x = y+3
2x - y = 5 ?

Answer 1

x = y+3
2x - y = 5

2(y+3) - y = 5
2y + 6 - y = 5
y = 5 - 6
so, y is equal to...?

Answer 2

-1

Answer 3

Great

Answer 4

x = y + 3 ---> y = x - 3
2x - y = 5 --> y = 2x - 5

y = y

x - 3 = 2x - 5
2x - x = 5 - 3
x = 2
y = -1

Answer 5

Therefore, (x,y) = (2,-1)
