Question

Please help its for algebra!

Answer 1

x - 2y = 32

Explanation:

Start with y + 7 = (1/2)(x - 18).

Clear out the fractions by mult. both sides by 2:

2y + 14 = x - 18

Subtract 2y + 14 from both sides, obtaining:

0 = x - 2y - 14 - 18, or

0 = x - 2y - 32

Then x - 2y = 32. This is in standard form.
