Question

Y=x-1 y=1/2x+1 whats the solution?

Answer 1

x = 4, y = 3

Explanation:

y = x - 1

y = 1/2 x + 1

y = y, so x-1 = 1/2x + 1

x - 1/2x = 1 + 1 --> 1/2x = 2

Multiply both sides by 2:

x = 4.

Plug x to find y

y = 4 - 1 = 3

You can check your answer by plugging x into both equations and seeing if they equal:

y = 1/2(4) + 1 = 3

You can also solve this by graphing if you want to.
