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!

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,
