Answer:

30 and 6

Explanation:

Let the numbers be x and y. Then

x+y=36
x−y=24

Adding the two equations together gives

2x=60

∴x=30

Substituting this back into either of the equations gives y=6

Sum means add.
difference means subtract.

x + y = 36
x - y = 24 Just to make it complete, I finish the problem. Add the two equations.
=======
2x = 60 Divide by 2
x = 60/2
x = 30

x + y = 36 Substitute for x
30 + y = 36 Subtract 30
y = 36 - 30
y = 6

So the solution point is (30,6)

What is the solution of log4x − 616 = 4? x = −2 x = 2 x = 3 x = 4

ivolga24 [154]

This is how to solve for log expressions.
First, do the arithmetic such that all that can be solved is in the other side, besides log.
There are different properties of log to help you solve log expressions.

log4x − 616 = 4
log4x = 620
Change how it is written to solve for x.
x^620 = 4
This makes no sense so we try again.

Or, this could be solved differently.
log 4x-6 16 = 4
(4x-6) ^4 = 16
256x - 1296 = 16
x = 5.125

Final answer: x = 5
