Answer:
3 (5x+7) = 75
15x + 21 = 75
15x + 21 - 21 = 75 - 21
15x = 54
x = 3.6
Step-by-step explanation:
Answer:
The Solution set is (x,y){(2,5)}
Step-by-step explanation:
The given equation is:
6x+4y=32
-6x+4y=8
We will use the elimination method:
By this method we will eliminate the variable x.
6x+4y=32
-6x+4y=8
________
8y=40
Divide both the sides by 8
8y/8=40/8
y=5
Now substitute the value of y in equation 2:
-6x+4y=8
-6x+4(5)=8
-6x+20=8
Move the constant value to the R.H.S
-6x=8-20
-6x= -12
Divide both the terms by -6
-6x/-6 = -12/-6
x= 2
The Solution set is (x,y){(2,5)}....
Answer:
-10.6 and 9/10
Step-by-step explanation:
Constants do not have any letter or variable so the ones with n or m are not constants
B-8. This is because -4 to 0 is 4 and then 0-4 is 4. 4+4=8
Answer:
<u>(x+9)^2</u> +<u> (y+6)^2</u>
