Ok so for starters you want to choose an equation and solve for a variable.
So, I am going to choose x from the first equation.
Add y to both sides and you get x=11+y
Next, substitute 11+y for x in the other equation so you get...
2(11+y) +10y=-6
Next distribute the 2 throug the 11 and the y
22+2y+10y=-6
12y=-28
y=-28/12
reduce this fraction to make this easier.
y=-7/3
Now plug in why to either of the equations to find x
x-(-7/3)=11
x+7/3=11
x=11-(7/3)
x=(33/3)-(7/3)
x=26/3
so x = 26/3 and y = -7/3
you can also check to see if this is correct by substituting each of these values into the equations.
Is there a restriction that the set must be positive? or whole numbers? Because negative numbers can be even, which makes your set an infinite list of numbers.
Natural numbers: P = {2, 4, 6, 8, 10}
Whole numbers: P = {0, 2, 4, 6, 8, 10}
All real numbers: P = {2n ;n ≤ 5}
Answer:
correct anwer=27
Step-by-step explanation:
the anwer for this equation comes out to be 27. As simple as it becomes on applying paranthesis to this equation therefore we get
8+(30/2)+4=27
we need to apply the paranthesis using the method of BODMAS.
which favours division over addition.
therefore,correct anwer is 27 and not 13
Answer:
x=-4
Step-by-step explanation:
Cross multiply to get:
3x=4(x+1)
3x=4(x+1)
3x=4x+4
x=-4
