1 answer:
VARVARA [1.3K]4 years ago
4 0

Answer:

x= 2.5

Step-by-step explanation:

We can use ratios to solve

AB          AD

------- = ----------

AC          AE

X          5

------- = ----------

x+1         7

Using cross products

7x = 5(x+1)

Distribute

7x = 5x+5

subtract 5x

7x-5x = 5x-5x+5

2x= 5

Divide by 2

2x/2 = 5/2

x = 2.5

Charra [1.4K]

Answer:

Remove 6 from both sides

4q+6=-14

4q/4=-20/4

q=-5
