Question

3x-y=2, Y=2x-1 substitude for y

Answer 1

x = 3

y = 7

Explanation:

3x - y = 2 Y = 2x - 1

3x - 2x - 1 = 2

x - 1 = 2

x = 3

Now put 3 in for x and solve for y

3(3) - y = 2

9 - y = 2

- y = -7

y = 7

Let's check

3(3) - 7 = 2

9 - 7 = 2

2 =2

So, x = 3 and y = 7 is the correct answer.
