Solve 3x+6y=18 for x

Mathematics
1 answer:
loris [4]4 years ago
5 0

Answer:

x=6-2y

Step-by-step explanation:

3x+6y=18

Subtract 6y from both sides of the equation.

3x=18−6y

Divide each term by 3 and simplify.

Divide each term in 3x=18−6y.

3x/3=18/3+−6y/3

Cancel the common factor of 3.

x=18/3+−6y/3

Simplify each term.

x=6−2y

Hope this helps! Plz mark as brainliest! :)

sarah has a solid wooden cube with a length of 4/5 centimeter. from eaxh of its 8 corners, she cuts out a smaller cube with a le
faltersainse [42]
First, calculate for the volume of the cube before each edges are cut.
                                    V = e³
where e is the length of each sides. Substituting the known value,
                                   V = (4/5 cm)³ = 0.512 cm³

Then, calculate for the volume of each of the small cubes cut out from the corners.
                                   V = (1/5 cm)³ = 0.008 cm³
Since there are 8 of these small cube, we multiply the volume by 8.
                                       8V = 8(0.008 cm³) = 0.064 cm³

Then, subtracting the volumes will give us an answer of <em>0.448 cm³</em>

4x + (-3) = 5x + 3?????
Bond [772]

Hi there! :)

\large\boxed{x = -6}

Solve for x:

4x + (-3) = 5x + 3

Adding a negative number is simply subtracting, therefore:

4x - 3 = 5x + 3

Subtract 4x from both sides:

4x - 4x - 3 = 5x - 4x + 3

-3 = x + 3

Subtract 3 from both sides:

-3 - 3 = x + 3 - 3

-6 = x
