Solve equations

Key Notes :

🎯 To solve for a variable, use inverse operations to undo the operations in the equation. Be sure to do the same operation to both sides of the equation.

Learn with an example

🎯 Solve for d.

d = 72 − 65

d = 

  • The variable d is already alone on the left side of the equation. Simplify the right side of the equation.
  • d = 72 − 65
  • d = 7 Simplify

🎯 Solve for t.

66 + 13 = t

t = 

  • The variable t is already alone on the right side of the equation. Simplify the left side of the equation.
  • 66 + 13 = t
  • 79 = t Simplify

🎯 Solve for j.

22 − 4 = j

j = 

  • The variable j is already alone on the right side of the equation. Simplify the left side of the equation.
  • 22 − 4 = j
  • 18 = j Simplify
