<h3>Answer:</h3>

<u>If AB = 12units, then</u>

A'B' = 1/2 × 12 = 6units.

<u>If C'D' = 5units, then</u>

CD = 2 × 5 = 10units.

9x-y=5<br> 7x-6y=5<br> Solve the system by the substitution method

qwelly [4]

9x - y = 5
7x - 6y = 5

Solve both equations for one variable. I'll solve for y.

9x - y = 5 Subtract 9x from both sides
-y = -9x + 5 Divide both sides by -1
y = 9x - 5

7x - 6y = 5 Subtract 7x from both sides
-6y = -7x + 5 Divide both sides by -6
y = $\frac{7}{6}$ x - $\frac{5}{6}$

Since both equations equal y, you can set them equal to each other and solve for x.

9x - 5 =<span> $\frac{7}{6}$ x - $\frac{5}{6}$ Multiply both sides by 6 to eliminate the fractions
54x - 30 = 7x - 5 Subtract 7x from both sides
47x - 30 = -5 Add 30 to both sides
47x = 25 Divide both sides by 47
x = </span> $\frac{25}{47}$

Now, plug that x-value into the x of either equation. I'll plug it into 9x - y = 5.

9x - y = 5 Plug in the x-value
9(<span> $\frac{25}{47}$ ) - y = 5 Multiply
</span> $\frac{225}{47}$ - y = 5 Subtract <span> $\frac{225}{47}$ from both sides
</span>-y = <span>0.21276595744 (I had to convert it to a decimal) Divide both sides by -1
y = -</span><span>0.21276595744

So, the answer to the system is (</span>0.53191489361, -<span>0.21276595744)</span>
