  1. Solving Linear Equations BY Nathaniel Jefferson EARU

  2. Solving Linear Equation Solve for the unknown variable by using the inverse operations

  3. Basic operation + addition - subtraction 3x multiplication X/5 division Inverse Operations Subtraction - Addition + Division ?/3 Multiply 5( ) 1. Identify THE BASIC – INVERSE STEP

  4. 2x multiplication +5 addition Divide by 2 2.Given 2x+5=45 , find x • SUBTRACT -5

  5. 2x+5-5=45-5 2X =40 2X/2 =40/2 X =20 Subtract 5 Divide by 2 X= the solution X=20 3.Find the basic operation and use the inverse operation on both sides of the equation.

  6. 2( )+5=45 2(20)+5=45 40 +5=45 45 = 45 ( the solution for x ) X = 20 2 ( 20 ) = 40 45 = 45 To Check by substitution

  7. To solve : Identify the basic operation + addition - subtraction ?( ) MULTIPLICATION ?/ division To solve : You must use the inverse operation - subtraction + addition division multiplication Quick Review

  8. Find the value for x in the following:Solve and check • 1. 7m-2=54 m= • 2. 2=6a-10 a= • 3. C/2+3=7 c= • 4. I/3 p+8=11 p= • 5. 21=2t+3 t= • 6. W/4 – 7 = 3 w=
