1. The problem statement, all variables and given/known data

Problem 20. Solve for x :

1.25x − 6 = x

1.25x −x = 6

(1.25 − 1)x = 6 On combining the like terms

on the left.

.25 x = 6

x = 24. On multiplying both sides

by 4.

2. Relevant equations

3. The attempt at a solution

Well i know x = 24. but how does 1.25 0- 1 = .25? how do i get 24x? why do i multiply both sides and why did i multiply them by 4?

My attempt

Problem 20. Solve for x :

1.25x − 6 = x

(1.25-x)

(1.25-1(x) = 6

1.24x = 6

(1.24 = 6 is 1.24 x 6 so i divide right?)

20.0x(rounded the nearest 10th..i think)

20.0x = x

x = 20.0x
