Help for the second answer it says express your answer as a decimal I need help and for a check in the 1st answer

x = -1.1

Step-by-step explanation:

3(5x - 8) = -5(-x + 7)

15x - 24 = 5x - 35

15x - 5x = -35 + 24

10x = -11

x = -11/10

x = -1.1

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 answer is simply just 6n add the two together as they have an n
