jim_thompson5910 · Answer

Solve for x

$$\Large \frac{CA}{CB} = \frac{DF}{DE}$$

$$\Large \frac{8+x}{8} = \frac{10+25}{10}$$

anonymous · Answer

what is the next step after that?

anonymous · Answer

@jim_thompson5910  is there another step?

jim_thompson5910 · Answer

yes there are many steps after that

you need to fully isolate x (get it by itself)

jim_thompson5910 · Answer

$$\Large \frac{CA}{CB} = \frac{DF}{DE}$$

$$\Large \frac{8+x}{8} = \frac{10+25}{10}$$

$$\Large \frac{8+x}{8} = \frac{35}{10}$$

$$\Large 10(8+x) = 8*35$$

$$\Large 80 + 10x = 280$$

I'll let you finish up
