Answer:

$x=0.5$

$y=anything$

Step-by-step explanation:

15−x+y=14−(−x−y)

15-x+y=14+x+y

Subtract 14 from both sides

1-x+y=x+y

Subtract y from both sides

1-x=x

Add x to both sides

1=2x

2x=1

Divide both sides by 2

x=0.5

$\displaystyle\\
\bf\\
log_{x+5} 36 = 2\\\\
\Longrightarrow~~(x+5)^2 = 36\\\\
(x+5)^2 = 6^2\\\\
x+5= 6\\\\
x = 6 - 5 = \boxed{\bold{1}}$

Arranging like terms; solve the linear system using eliminationlly - 3x = 18- 3x = -16y + 33

DENIUS [597]

Solution

For this case we can do the following:

11y - 3x = 18

16y -3x = 33

We can multiply the first equation by -1 and we got:

-11y +3x =-18

16y -3x = 33

_______________

16y -11y = 33-18

5y = 15

y= 15/5 = 3

And then solving for x we got

x = -(18 -11*3)/ 3= -15/3 = 5
