Y=x+3 2x+y=-6 Find the solution :

Mathematics
1 answer:
Charra [1.4K]2 years ago
3 0

Answer:

Your solution is (-3,0)

Step-by-step explanation:

Hi,

We know what Y is, so we can plug it into the second equation.

2x + y = -6

2x + (x + 3) = -6

Now, add the like terms...

3x + 3 = -6

3x = -9

x = -3

Now, plug x back in to find y.

y = x + 3

y = (-3) + 3

y = 0

Your solution is (-3,0)

Hope this helps :)

3x - 3y = 9 and x + 3y = 12 <br> Elimination
Firlakuza [10]

Answer:

x=5.25,y=2.25

Step-by-step explanation:

We can add the two equations to eliminate the variable y and solve for x:

3x-3y+x+3y=9+12

4x=21

x=5.25

Now, we can use substitution to solve for y:

x+3y=12 (given)

5.25+3y=12

3y=12-5.25

=6.75

y=2.25

Hope this helps :)

Using radicals , write an equivalent expression for the expression 2 1/3
liq [111]
I'm assuming that the 1/3 is an exponent.

If so, then 2^{1/3} = \sqrt[3]{2}

Which is the cube root of 2. Raising any value to the 1/3 power is the same as taking the cube root.
