(x-1)/5 = (4x + 2)/35
lets start off by multiplying each side by 5
(x-1) = 5(4x + 2)/35
then let's multiply both sides by 35
35(x-1) = 5(4x + 2)
now let's distribute the coefficients (5 and 35) into everything in the brackets
35 times x is 35x
35 rimes 1 is 35
5 times 4x is 20x
5 times 2 is 10
(35x - 35) = (20x + 10)
we can add 35 to both sides
35x = 20x + 45
then subtract 20x on both sides
15x = 45
then divide both sides by 15
x = 3
