Question

Solve for X: 4x - 19 = 21

Answer 1

`\huge{ \fbox{ \sf{x = 10}}}`

Explanation:

`\bigstar{ \sf{ \: \: 4x - 19 = 21}}`

`\underline{ \underline{ \mathfrak{Let's \: solve}}} :`

`\text{Step \: 1} : \sf{Move \: 19 \: to \: right \: hand \: side \: and \: change \: it's \: sign}`

`\mapsto{ \sf{4x = 21 + 19}}`

`\text{ Step \: 2} : \sf{Add \: the \: numbers : 21 \: and \: 19}`

`\mapsto{ \sf{4x = 40}}`

`\text{Step \: 3} : \sf{Divide \: both \: sides \: by \: 4}`

`\mapsto{ \sf{ (4x)/(4) = (40)/(4) }}`

`\text{Step \: 4} : \sf{Calculate}`

`\mapsto{ \sf{x = 10}}`

Hope I helped!

Best regards! :D

Answer 2

x = 10

Explanation:

4x - 19 = 21

Add 19 to each side

4x - 19+19 = 21+19

4x =40

Divide each side by 4

4x/4 = 40/4

x = 10
