How do I solve The sum of a number and 3 is subtracted from 10 the result is 5

meriva

State the given in the question

Given that the sum of a number and 3 is subtracted from, the result is 5

State what is to be found in the question

We are to find the number. In other to achieve this, we would follow the steps below:

Step 1: Represent the number with an unknown

Let x represent the number

Step 2: Interpret the given statement mathematically

If x is the number, then the sum of the number and 3 would be

$x+3$

Then the sum of a number and 3 subtracted from 10 would be

$10-(x+3)$

Finally, when the sum of a number and 3 subtracted from 10, the result is 5, would be

$10-(x+3)=5$

Step 3: Solve for x in the mathematical interpretation of the given statement

The value of x is as calculated as shown below:

$\begin{gathered} 10-(x+3)=5 \\ \text{Open the bracket or the parenthesis} \\ 10-x-3=5 \\ \text{collect like terms} \\ 10-3-5=x \\ 7-5=x \\ 2=x \\ \text{Therefore:} \\ x=2 \end{gathered}$

Hence, the number is 5

9) -9x - 13 - y = 0<br> 7=-y-3x

Debora [2.8K]

Answer:

The value of x and y is ,

x = $\frac{-5}{3}$ and y = 2

Step-by-step explanation:

The given two linear equation can be written as ,

y + 9x = -13 ....1 and

y - 3x = 7 .....2

Put the value of y from eq 1 into eq 2

i.e (-13 -9x) - 3x = 7

or, -12x = 7 +13

Or, -12x = 20

i.e X = $\frac{-5}{3}$

Now put t his value of x in any above two linear equation

Let put this value on eq 2 to get value of y

so its can be writen as.

y = 3x + 7

or, y = 3( $\frac{-5}{3}$ ) + 7

or, y = -5 +7

i.e Y = 2

Hence the value of x and y is , x = $\frac{-5}{3}$ and y = 2 Answer

I'm trying to find how to get the answer to (s+12)+(3s-8)

7nadin3 [17]

(S + 12) + (3s - 8)
= s + 12 + 3s - 8
= s + 3s + 12 - 8
= 4s + 4
