Let, the number = x

Then, 2x + 3 = 4x - 5

2x - 4x = -5 - 3

-2x = -8

x = 8/2

x = 4

In short, the number would be: 4

Hope this helps!

2n+3=4n-5 subtract 4n from both sides

-2n+3=-5 subtract 3 from both sides

-2n=-8 divide both sides by -2

n=4

Dividing Mixed fractions

Komok [63]

First you would make the mixed fractions into improper fraction by multiplying the denominator and the whole number, then adding the numerator. Then you would flip the second fraction and multiply.
Ex. 1 1/2 ÷1 1/2
1st. 3/2÷3/2
2nd: 3/2×2/3
3rd 3/2x2/3=1

ser-zykov [4K]

The sale price S (in dollars) of an item is given by the formula

S=L−rL , where L is the list price (in dollars) and r is the discount rate.

Since, S = L -rL

rL = L -S

r = $\frac{L-S}{L}$
