Solve the two-step equation. -0.45x + 0.33 = -0.66
What is the solution?
x = -2.2
x = -1.4
x = 1.4
x = 2.2

Step-by-step explanation:

-0.45x + 0.33 = -0.66  subtract 0.33 both sides

-0.45x = -0.66 - 0.33    simplify

-0.45x = -0.99               multiply both sides by 100

-45x = -99                   divide -45 both sides

x = -99 / -45                  simplify

x = 11/5 or 2.2

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
