Question

We get the same result if we multiply a number by 4 or if we multiply the number by 7 and then add 9. Find the number.

Answer 1

To find the number that gives the same result when multiplied by 4 or when multiplied by 7 and then added 9, we solve the equation 4x = 7x + 9, yielding x = -3.

Step-by-step explanation:

The student is asking to find a number that when multiplied by 4 gives the same result as when the number is multiplied by 7 and then have 9 added to the result. This can be represented by the equation 4x = 7x + 9. To solve for x, follow these steps:

Subtract 7x from both sides: 4x - 7x = 9.

Simplify by combining like terms: -3x = 9.

Divide both sides by -3: x = -3.

The number we are looking for is -3.

Answer 2

I think it’s when you multiply by 7 then add 9 but it’s just what I think.
