How do i solve -3x-(-2)=(-10)

Step-by-step explanation:

First, let's remove the parentheses and distribute any minus signs that are present outside of the parentheses:

Next, let's subtract from both sides to isolate the terms with an on the left-hand side of the equation:

Finally, let's divide both sides by to get the by itself on the left-hand side of the equation:

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:

the correct option is b
