4/5G + 42 = 2.8G + 18
Plz solve with an explanation

12

Step-by-step explanation:

Simplify  \frac{4}{5}G

5

4

G  to  \frac{4G}{5}

5

4G

.

\frac{4G}{5}+42=2.8G+18

5

4G

+42=2.8G+18

Multiply both sides by 5.

4g + 210 = 14g + 90

Simplify  

 14G + 90 - 4G to 10G + 90

Subtract 90 from both sides.

210-90=10G210−90=10G

Simplify  210-90210−90  to  120120.

120=10G120=10G

Divide both sides by 1010.

\frac{120}{10}=G

10

120

=G

Simplify  \frac{120}{10}

10

120

  to  1212.

12=G12=G

Switch sides.

G=12G=12

SORRY ABOUT ALL THIS WORK...

Its 12

Step-by-step explanation:

The person up there explains it good

d

step-by-step explanation:

d

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:
