Solve for x if EF = 2x + 7 and FG = 7x –9<br><br> help please I'll give brainliest
s2008m [1.1K]

Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

\therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)

AB = BC.... (given)

\implies \frac{AB}{BC} = 1..... (2)

From equations (1) & (2)

1 =\frac{EF}{FG}

{FG}={EF}

Therefore,

7x - 9 = 2x + 7

7x - 2x = 9 + 7

5x = 16

x = 16/5

x = 3.2
