Its on the screenshot :) plz help
andrey2020 [161]

Answer:

a = -6, b = 48

Step-by-step explanation:

a(3x - 8) = b - 18x --> 3ax - 8a = b - 18x, then comparing two sides for the x part, only 3ax and -18x has x, so there are equivalent 3ax = -18x, solve for a = -6, then the part left is -8a = b, let a = -6 into the equation, get -8 * -6 = b = 48.
