What is the solution to the system of equations X+y=5 X-2y=2 (_,_)

1 answer:

5 0

X + y = 5 => 2x + 2y = 10
x - 2y = 2
_________(+)
3x = 12 => x = 12 / 3 => x = 4 => y = 5 - 4 => y = 1
The solution to the system of equations is ( 4 , 1 ).

What is the following is the solution to the equation 25^(z+2) = 125

maksim [4K]

First, rewrite the equation $25^{z+2} = 125$ with the base equal to 5. Note that:

$25=5^2;$
$125=5^3;$
$25^{z+2}=(5^2)^{z+2}=5^{2\cdot (z+2)}.$

Then

$5^{2\cdot (z+2)}=5^3.$

Since the bases are equal, you have that powers are equal too:

$2\cdot (z+2)=3,\\ \\2z+4=3,\\ \\2z=3-4,\\ \\2z=-1,\\ \\z=-\dfrac{1}{2}.$

Answer: $z=-\dfrac{1}{2}.$
