SOLUTION :

Solve and check the following two-steps linear equation.

1. 15 = 2x + 7

Solve,

  • 15 = 2x + 7
  • 2x = 15 - 7
  • x = 8/2
  • x = [tex]{\boxed{\green{\sf{4 }}}}[/tex]

Check ☑

  • 15 = 2x + 7
  • 15 = 2(4) + 7
  • 15 = 8 + 7
  • 15 = 15 ✔️

Answer:- [tex]{\boxed{\green{\sf{\therefore\:4 }}}}[/tex]

2. 7m - 3 = -24

Solve,

  • 7m - 3 = -24
  • 7m = -24 + 3
  • m = -21/7
  • m = [tex]{\boxed{\green{\sf{-3}}}}[/tex]

Check ☑

  • 7m - 3 = -24
  • 7(-3) - 3 = -24
  • -21 - 3 = -24
  • -24 = -24 ✔️

Answer:- [tex]{\boxed{\green{\sf{\therefore\:-3}}}}[/tex]
