Answer:
x=-3/5y+3
Step-by-step explanation:
Let's solve for x.
5x+3y=15
Step 1: Add -3y to both sides.
5x+3y+−3y=15+−3y
5x=−3y+15
Step 2: Divide both sides by 5.
5x/5 = -3y+15/5
Answer
x=-3/5y+3
Answer:
The required linear equation is m + ( 3 m) = 24 : m = number of forks
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Write a system of linear equation that represents this situation
.
A drawer contains 24 spoons and forks. There are three times as many spoons as forks.
Now, according to the given question:
Let us assume the number of forks = m
So, the number of spoons = 3 x ( Number of forks ) = 3 x (m) = 3 m
Now, Number of Spoons + Number of forks = 24
⇒ m + ( 3 m) = 24
Hence the required linear equation is m + ( 3 m) = 24
here : m = number of forks
Answer:
Excluded Value : 3 and -5
Step-by-step explanation:
hello :
Excluded Value : and
the excluded value when : x²+2x-15=0
(
x²+2x+1)-1-15=0
means : (x+1)²-16=0 (x+1)²-4² = 0
by identity : a²-b² =(a-b)(a+b)
(x+1-4)(x+1+4) =0 so : (x-3)(x+5) =0 means : x-3=0 or x+5=0
x=3 or x= -5
Excluded Value : 3 and -5
Answer:
no
