Someone help I’m taking a test- Evaluate the expression below when x = 2 and z = 12
3
Z + 5x

I don’t know the answer but can someone tell me what it is please?

3/z+5x=567

Step-by-step explanation:

3/z+5x=5678

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:
