Step 1: Y is equal to \frac{3}{4}x + 2 so where ever you see a y in the equation 3x - 4y = -5 replace it with \frac{3}{4}x + 2

3x - 4(\frac{3}{4}x + 2) = -5

Now all your variables are x and you can solve for x

Step 2: Distribute for to the numbers in the parentheses

3x - 3x - 8 = -5

Step 3: Combine like terms

0x - 8 = -5

0x = 3

Step 4: Isolate x

0x/0 = 3/0

3/0 is undefined

^^^ This means that there is no answer

If you look at the graph below you can see that these lines are parallel and therefore have no intersection point

Hope this helped!
