Let the three consecutive number be x,x+1 and x+2.
It is given sum of three consecutive numbers is 46.
So,x+x+1+x+2=46
3x+3=46.
Subtracting 3 both sides
3x=46-3
3x=43.
x= 
Since
is not an integer there is no true answer to this problem.
You could use a method called cross products to solve this proportional equation. What you would do is multiply 3.4*7.7 =2.17*x
If multiplied correctly, your equation should be 26.18 = 2.17x
You are trying to get the variable alone on one side. To do this, you have to undo the multiplication of the coefficient. The opposite of multiplication is division, so you would divide both sides by 2.17.
If done correctly, your equation should now be x=<span>12.064516129
However, this can be rounded to x= approximately 12.066

♡Let's solve this Step-By-Step!<span>♡
</span>♡<span>Question:
A=2(L+w)
♡</span>To solve for W we need to flip the equation like so:
<span><span>2l</span>+<span>2w</span></span>=<span>a
</span>
♡Now a<span>dd -2l to both sides:
</span><span><span><span>2l</span>+<span>2w</span></span>+<span>−2l</span></span>=<span>a+<span>−<span>2l
</span></span></span><span>2w</span>=<span>a−<span>2<span>l
</span></span></span>
♡<span>Divide both sides by 2:
</span><span><span>2w/</span>2</span>=<span><span>a−<span>2l/</span></span><span>2
</span></span>♡<span>Your answer shall be:
</span>w=<span><span><span>1/2</span>a</span>−l

♡Hope this helps!♡
