Let's represent the number as "x".
The equation for "three times a number, minus 9 is equal to two times the number plus 8" can be written as:
3x - 9 = 2x + 8
To solve for "x", we can start by isolating the variable.
Subtracting 2x from both sides of the equation:
3x - 2x - 9 = 2x - 2x + 8
x - 9 = 8
Next, we can add 9 to both sides of the equation:
x - 9 + 9 = 8 + 9
x = 17
Therefore, the number we are looking for is 17.
write the following as an equation. then solve
three times a number, minus 9 is equal to two times the number plus 8 find the number.
