3x - 7 + 4x = 28 7x - 7 = 28 I added 4x and 3x to get 7x 7x = 35 I subtracted 7 from both sides x = 5 I divided by 7 on both sides

7x/4 = 1/8 (7x/4) x (8) = (1/8) x (8) 14x = 1 x = 1/14

3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x

Look for the GCF. 7, 14 and 21 all have 7 as a common factor. Divide that out. 7x divided by 7 = x 21 divided by 7 = 3 14y divided by 7 = 2y 7x + 21 + 14y = 7(x + 3 + 2y)

(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8

7x-4 = 3x+36Add 4, it cancels out.. So,7x = 3x+40Now subtract 3x from 7x..4x = 40..40 divided by 4 is 10So, X= 10

7x / 2 = 3 7x=2(3) 7x=6 x=6/7 The answer is x=6/7
