Answer:

x = 1

Step-by-step explanation:

Step 1: Write equation

9 - 2x = 7x

Step 2: Solve for x

Add 2x on both sides: 9 = 9x

Divide both sides by 9: x = 1

Step 3: Check

Plug in x to verify it's a solution.

9 - 2(1) = 7(1)

9 - 2 = 7

7 = 7

Answer:

y = 3 $\sqrt{7}$

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

$\frac{y}{9}$ = $\frac{7}{y}$ ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = $\sqrt{63}$ = 3 $\sqrt{7}$
