1. Add y to each side
That will get you 3x=8+y
2. Subtract 8 on each side
That will get you y=3x-8
Answer:
x = 28/3
Step-by-step explanation:
We can solve this problem by using similar triangles:
Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.
Now we can set up ratios and solve:
13/7 = (x+8)/x
multiply both sides by x:
13x/7 = x+8
Multiply both sides by 7:
13x = 7x + 56
move the 7x over and divide by 6:
6x = 56
x = 28/3
