Answer:
Step-by-step explanation:
if 36^12-m=6^2m , find the value of m
To make the exponents equal , we need to get the same base.
The base of both sides of equation are not same.
36 can be written as 6^2
now base of both sides are same . so we equate the exponents
add 2m on both sides
divide by 4 on both sides
The value of m is 6
Answer:
(-13, -4)
Step-by-step explanation:
It is about as easy to try the solutions as it is to find them from scratch.
__
However, we can determine which one it is by adding twice the second equation to the first.
(-2a +3b) +2(a -4b) = (14) +2(3)
-5b = 20
b = -4 . . . . . . matches the first choice
