twice the difference of a number and 3 is equal to 3 times the sum of a number and 2.
We've got 2 algebraic expressions here. Let's take them in parts.
Left side algebraic expression: twice the difference of a number and 3
This means we have an equation, where we set the left side algebraic expression equal to the right side algebraic expression using the equal sign (=) to get our answer
2(x - 3) = 3(x + 2)

Left side algebraic expression: twice the difference of a number and 3
- The phrase a number means an arbitrary variable, let's call it x.
- The word difference means we subtract 3 from the variable x
- x - 3
- Twice this difference means we multiply (x - 3) by 2
- 2(x - 3)
- The phrase a number means an arbitrary variable, let's call it x.
- The word sum means we add 2 to the variable x
- x + 2
- 3 times the sum means we multiply (x + 2) by 3
- 3(x + 2)
This means we have an equation, where we set the left side algebraic expression equal to the right side algebraic expression using the equal sign (=) to get our answer
2(x - 3) = 3(x + 2)
