AVprozaik [17]

Answer:

$x + y = 79$ and

$x - y = 25$

$(x,y) = (52,27)$

Step-by-step explanation:

Let the variables be: x and y

The equations can be modelled as:

$x + y = 79$ and

$x - y = 25$

To solve for x and y, we have:

Make x the subject in $x - y = 25$

$x = 25 + y$

Substitute $x = 25 + y$ in $x + y = 79$

$25 + y + y = 79$

$25 + 2y = 79$

Collect like terms

$2y = 79 - 25$

$2y = 54$

Divide both sides by 2

$y = 27$

Substitute $y = 27$ in $x = 25 + y$

$x = 25 + 27$

$x = 52$

So, we have:

$(x,y) = (52,27)$

If A+B = 76 & A -B = 38 What is A/B?

Igoryamba

$A+B=76\\
A-B=38\ \ --->\ \ A=38+B\\\\
38+B+B=76\\
38+2B=76\ \ | subtract\ 38\\2B=38\ \ \ | divide\ by\ 2\\
B=19\\A=57\\\\
\frac{A}{B}=\frac{57}{19}=3$
