Answer/Step-by-step explanation:
The corresponding side lengths of two triangles are always equal. Apply this in solving for x
4. 
Cross multiply

6x = 45
divide both sides by 6
y = 7.5
5. 
Cross multiply

8x = 110
divide both sides by 8
x = 13.75
6. 
Cross multiply

7x = 48
divide both sides by 7
x = 6.86 (nearest hundredth)

Step-by-step explanation:
So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:
