Answer:

4 & 8

Step-by-step explanation:

x-y = 4 -> x = 4+y

x+y = 12 = 4+y+y -> 4+2*y = 12

-> 2*y = 8 -> y = 4

-> x = 4+y = 8

X(5)+2=244<br>help pls<br>(^_^)

arsen [322]

Simplify both sides of the equation

5x+2=244

Subtract 2 from both sides

5x+2−2=244−2
5x=242

Divide both sides by 5

$\frac{5x}{5} = \frac{242}{5}$

Answer

$\: x = \dfrac{242}{5}$

$\: x = 48.4$
