HELP

4a + 14

Step-by-step explanation:

Start by pairing like perms together:

10a, -6a

-37, 51

Next, rearrange the expression so that the like term pairs are next to each other:

10a-6a + -37+51

10a-6a + 51-37 (You can rewrite -37+51 as 51-37, while making sure to keep the "-" sign or negative sign with the 37)

10a-6a is 4a and 51-37 is 14

Thjerefore the simplified version of the given expression is 4a + 14.

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:
