Question

Solve the equation for x.
​

Answer 1

x = 28

Explanation:

Multiply through by 28 to clear the fractions

28 is the lowest common multiple of 4 and 7

7x - 56 = 4x + 28 ( subtract 4x from both sides )

3x - 56 = 28 ( add 56 to both sides )

3x = 84 ( divide both sides by 3 )

x = 28

Answer 2

x=1

Explanation:

multiply both sides by 28 (it is the Least Common Multiple) which would bring your equation to be

7x-2= 4x+1

3x=3

x=1
