Steps:
So firstly, let's translate our sentence (let x = unknown number):
- "negative three times a number": -3x
- "is the same as": =
- "four less than the product of negative seven and five": (-7 × 5) - 4
Putting it together the algebraic equation is [tex]-3x=(-7*5)-4[/tex]
From here we can solve for x as such:
[tex]-3x=(-7*5)-4\\-3x=-35-4\\-3x=-39\\x=13[/tex]
Answer:
In short:
- The equation is [tex]-3x=(-7*5)-4[/tex]
- The unknown number is 13.
