Answer:

x=-1

Step-by-step explanation:

5x-2x-7=-10

3x-7=-10

3x-7+7=-10+7

3x=-3

x=-1

[tex]\text{Hey \: there!}[/tex]

[tex]\text{5x - 7 - 2x = 10}[/tex]

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

[tex]\bf{(5x - 2x) \: which \: gives \: us \: 3x}[/tex]

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

[tex]\text{3x - 7 + 7 = 10 + 7}[/tex]

  • Cancel out

[tex]\bf{ - 7 + 7 \: because \: it \: gives \: you \: 0}[/tex]

[tex]\bf{10 + 7 = 17}[/tex]

  • New equation:
  • [tex]\bf{3x = 17}[/tex]
  • Divide by 3 on both sides

[tex] \frac{3x}{3} = \frac{17}{3} [/tex]

  • Cancel out
  • [tex] \frac{3x}{3} \: \bf{because \: it \: gives \: you \: 1 \: and \: not \: x \: }[/tex]

[tex]\text{we \: cant \: divide \: 17 \: from \: 3 \: because \: itll \: give \: us \: a \: decimal}[/tex]

[tex]\boxed{\bf{thus \: your \: answer \: is \: \bf{ \frac{17}{3} }}}[/tex]

Good luck on your assignment and enjoy your day!
