Write the word sentence as an equation and solve it.

The difference of 2.1 and twice a number \( p \) is negative 4.7.

2.1-2p= -4.7
they said the difference of 2.1 and twice a number p. which I'm assuming letter p, but anyway. difference means subtraction and twice mean multiplication so 2p
that's why we have 2.1-2p= -4.7

The correct equation representing the given sentence is:
2.1 − 2 p = − 4.7
To solve for p , follow these steps:
1. Isolate the term containing p by adding 2 p to both sides of the equation:
2.1 = 2 p − 4.7
2. Add 4.7 to both sides to isolate the variable p :
2.1 + 4.7 = 2 p
6.8 = 2 p
3. Divide both sides by 2 to solve for p :
2 6.8 ​ = p
p = 3.4
Therefore, the number p is 3.4.
