Simplify by Combining Like Terms then solve
4x + 3x + 5 = 47
Next Step
. What happened?
7x + 5 = 47
7x = 42
...
x = 6

1. 4x+3x were added together because they are like terms

2. We subtracted 5 from both sides of the equation

3. We divide both sides of the equation by seven

Step-by-step explanation:

I hope this is what you were looking for... Good luck!

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:
