Answer:

x = 3

Step-by-step explanation:

  1. Subtract 15 from each side, so it now looks like this: 21 = 7x
  2. Divide each side by 7 to cancel out the 7 next to x. It should now look like this: 3 = x

I hope this helps!

Answer:

[tex] \huge{ \fbox{ \text{x = 3}}}[/tex]

Step-by-step explanation:

[tex] \star{ \sf{ \: 36 = 15 + 7x}}[/tex]

[tex] \text{Step \: 1 \: : Swap \: the \: side \: of \: the \: equation}[/tex]

[tex] \longmapsto{ \sf{15 + 7x = 36}}[/tex]

[tex] \text{Step \: 2 \: : Move \: 15 \: to \: right \: hand \: side \: and \: change \: it's \: sign}[/tex]

[tex] \longmapsto{ \sf{7x = 36 - 15}}[/tex]

[tex] \text{Step \: 3 \: : Subtract \: 15 \: from \: 36}[/tex]

[tex] \longmapsto{ \sf{7x = 21}}[/tex]

[tex] \text{Step \: 4 \: : Divide \: both \: sides \: by \: 7}[/tex]

[tex] \longmapsto{ \sf{ \frac{7x}{7} = \frac{21}{7} }}[/tex]

[tex] \text{Step \: 5 \: : Calculate}[/tex]

[tex] \longmapsto{ \sf{x = 3}}[/tex]

The value of x is 3

Hope I helped!

Best regards! :D
