Answer 2

`\text{Hey \: there!}`

`\text{5x - 7 - 2x = 10}`

• First you'll have to COMBINE all of your like terms

`\bf{(5x - 2x) \: which \: gives \: us \: 3x}`

• New equation becomes:
• 
  `\bf{3x - 7 = 10}`
• Add by 7 on your sides

`\text{3x - 7 + 7 = 10 + 7}`

• Cancel out

`\bf{ - 7 + 7 \: because \: it \: gives \: you \: 0}`

`\bf{10 + 7 = 17}`

• New equation:
• 
  `\bf{3x = 17}`
• Divide by 3 on both sides

`(3x)/(3) = (17)/(3)`

• Cancel out
• 
  `(3x)/(3) \: \bf{because \: it \: gives \: you \: 1 \: and \: not \: x \: }`

`\text{we \: cant \: divide \: 17 \: from \: 3 \: because \: itll \: give \: us \: a \: decimal}`

`\boxed{\bf{thus \: your \: answer \: is \: \bf{ (17)/(3) }}}`

Good luck on your assignment and enjoy your day!
