Three less than twice what number is -7?

2X-3=-7
+3. +3
2X = -4
/2. /2
x=-2
X = what number

To solve for this, we need to make this an equation. I will rewrite the question, and then write in parenthesis alongside it the equation.
Three less (-3) than twice what number (2x) is (=) -7 (-7).
Now rewrite what's in parenthesis.
2x - 3 = -7
To solve for this, we need to get 2x by itself and then simplify if possible.
Add 3 to both sides.
2x = -4
Divide both sides by 2.
x = -2.
Your number is -2.
I hope this helps!
