Answer:

x = \frac{c+d}{a-b}

Step-by-step explanation:

Given

ax - c = bx + d ( collect the terms in x together )

Subtract bx from both sides

ax - bx - c = d ( add c to both sides )

ax - bx = c + d ← factor out x from each term on the left side

x(a - b) = c + d ← divide both sides by (a - b )

x = \frac{c+d}{a-b}

Find the measure of
koban [17]

Answer:

m∡GHI = 21°

Step-by-step explanation:

Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.

That means you can set them equal to each other

x + 7 = 3x - 21

x = 14

Now plug x into GHI

14 + 7 = 21

m∡GHI = 21°
