Answer:

3 - a

Step-by-step explanation:

Given that when you add two numbers together the result is 3.

Let "x" represent that lesser number.

Thus:

a + x = 3

To make x the subject of the formula. Subtract a from both x.

a + x - a = 3 - a

x = 3 - a

Therefore, the expression that represents the lesser number, x, is:

3 - a

Make x the subject of h = 4(x + 3y) + 2<br>​
ratelena [41]
H = 4(x + 3y) + 2
H = 4x + 12y + 2
H - 12y - 2 = 4x
(H - 12y - 2) / 4 = x or 1/4H - 3y - 1/2 = x

Rearrange your equation to isolate a:(a+b/c)(d-e)=f
sukhopar [10]
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:

<span>((a+b/c)(d-e)=f) 1/(d-e)

</span>(a+b/c = f/(d-e))c

a+b = fc/(d-e)

a = [fc/(d-e)] - b

Hope this answers the question.
