Question

Please I need help! Write the equation for:

if you subtract 12 from my number and multiply the difference by -3 the result is -54. What is my number?

Answer 1

x=30

Explanation:

Make the unknown number x, use the equation (x-12)*-3 = -54, use the distributive property to make it -3x+36 = -54. Next, subtract 36 from both sides, to get -3x=-90, divide by -3 to get x=30

Answer 2

-3(x-12)=-54

Explanation:

So let x be the number

So -3(x-12)=-54

Here’s x:

So dividing both sides by -3, we get x-12=18. So x=30
