Ten is equal to two times a number plus 3.6.

3.2

Step-by-step explanation:

Make an equation!

10=2x+3.6

isolate the variable:

6.4=2x

divide by 2

3.2=x

i hope this helps!

3.2

Step-by-step explanation:

10= 2x + 3.6

subtract 3.6 from both sides

2x = 6.4

divide both sides by 2

x = 3.2

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
