Hi my lil bunny!

A) Let's solve for x. $-3x-7y=-66$

Step 1: Add 7y to both sides.

$-3x - 7y + 7y = -66 + 7y \\-3x = 7y - 66$

Step 2: Divide both sides by -3.

$\frac{-3x }{-3} = \frac{7y - 66}{-3}$

$x = \frac{-7}{3}y + 22$

Answer : $\frac{-7}{3}y + 22$

~~~~~~~~~~~~~

B) Let's solve for x. $-10x-7y=-24$

Step 1: Add 7y to both sides.

$-10x - 7y + 7y = -24 + 7y \\-10x = 7y - 24$

Step 2: Divide both sides by -10.

$\frac{-10x}{-10} = \frac{7y - 24}{-10}$

$x = \frac{-7}{10}y + \frac{12}{5}$

Answer : $\frac{-7}{10}y + \frac{12}{5}$

Then add the whole numbers

4 + 3 = 7

Then add the mixed number to the whole number

7 + 1 4/7 = 8 4/7
