16 + 1/3x = 3x
16 = 3x - 1/3x
16 = 9/3 x - 1/3 x
16 = (<span>9 x - 1 x)/3
</span>16(3) = 8x
48 = 8x
x = 6

aksik [14]

Answer:

<h2>x=-9</h2>

solution,

<em>5x + 8 - 3x =  - 10 \\ or \: 5x - 3x + 8 = -10 \\ or \: 2x + 8 = -10 \\ or \: 2x = -10 - 8 \\ or \: 2x = -18\\ or \: x =  \frac{-18}{2 }  \\ x = -9</em>

<em>hope</em><em> </em><em>this</em><em> </em><em>helps</em><em>.</em><em>.</em>

<em>Good</em><em> </em><em>luck</em><em> on</em><em> your</em><em> assignment</em>

Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth.
lakkis [162]
\sf 5x+2y=21
\sf -2x+6y=-34

We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':

\sf -2x+6y=-34

Subtract 6y to both sides:

\sf -2x=-6y-34

Divide -2 to both sides:

\sf x=3y+17

Plug in 3y + 17 for 'x' in the first equation:

\sf 5x+2y=21

\sf 5(3y+17)+2y=21

Distribute 5:

\sf 15y+85+2y=21

Combine like terms:

\sf 17y+85=21

Subtract 85 to both sides:

\sf 17y=-64

Divide 17 to both sides:

\boxed{\sf y\approx -3.8}

This is the y-coordinate of the solution.

Here is a system of linear equations: y = 3x + 4 y = 3x - 7 How many solutions, if any, does this system have?
marysya [2.9K]

Answer:

Step-by-step explanation:

y = 3*x  + 4

y = 3*x -   7

Each one of the above equations is the equation for a straight line.

The solution for such a system is the point P ( x₀ , y₀ ) which coordinates belong to both straight lines. According to this, there is only one solution for that system ( only one point of intersection). The intersection of a pair of straight lines either can occur or not depending on the slope of the lines, if they have the same slope they are parallel, then they did not touch each other ever. How can m,  be identified in the straight line equation??,   just by looking at the coefficient of x.  

The two equations have slope 3 they are parallel then there is not a solution ( there is not a common point to both equations)

The answer is correct? If it’s wrong please explain me how to solve it :’)
cricket20 [7]

Answer:

48

Step-by-step explanation:

x = -2 y =3

3x² - 2xy²

3(-2)² -2(-2)(3)²

square first

3*4 -2(-2)*9

multiplty from left to right

12-2(-2)*9

multiply from left to right again

12 -(-36) subtract using rule for integers that double minus is plus

12 + 36

48
