Solve the equation. SHOW your work. SHOW which properties of equality you used to solve each equation.

4.1 x + 1.2 = 9.4

Answer 1

Answer:
`x=2`

Move all terms to the left

`4.1x+1.2-(9.4)=0`

Add all the numbers together, and all the variables

`4.1x-8.2=0`

Move all terms containing x to the left, all other terms to the right

`4.1x=8.2\\x=8.2/4.1\\x=2`

Answer 2

`4.1x + 1.2 = 9.4 \\ 4.1x = 9.4 - 1.2 \\ 4.1x = 8.2 \\ (4.1x)/(4.1) = (82)/(4.1) \\ x = 2`
