Answer:
Its the first option.
Step-by-step explanation:
3x + y = 5
5x - 4y = -3
From equation 1:
y = - 3x + 5
Substituting for y:
5x - 4(-3x + 5) = -3
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:
what do you need solved
Step-by-step explanation:
Answer:
-4 and 9
Step-by-step explanation:
factored
(x - 9)(x + 4) = 0
with this x*x - 5x - 36 = 0
so x = 9 or x = -4
