Step-by-step explanation:
[tex]{ \tt{20x + 5 = 24x - 1}}[/tex]
» Subtract 20x from either sides [ subtraction rule of equality ]
[tex]{ \tt{(20x + 5){ \green{ - 20x}} = (24x - 1){ \green{ - 20x}}}} \\ { \tt{5 = 4x - 1}} \\ { \tt{4x - 1 = 5}}[/tex]
» Add 1 to either sides [ addition rule of equality ]
[tex]{ \tt{(4x - 1){ \green{ + 1}} = 5{ \green{ + 1}}}} \\ { \tt{4x = 6}} \\ { \tt{x = \frac{6}{4} }}[/tex]
» Reduce the fraction
[tex]{ \tt{x = \frac{3}{2} }} \\ \\ { \tt{x = 1 \frac{1}{2} \: \: or \: \: 1.5}}[/tex]
