What is the value of x in the equation 34x+2=54x−6 ?
elixir [45]

Answer:

The value of x in the equation is: x=\frac{2}{5}

Step-by-step explanation:

Given the equation

34x+2=54x-6

Subtract 2 from both sides

34x+2-2=54x-6-2

34x=54x-8

Subtract 54x from both sides

34x-54x=54x-8-54x

-20x=-8

Divide by both sides by -20

\frac{-20x}{-20}=\frac{-8}{-20}

x=\frac{2}{5}

Therefore, the value of x in the equation is: x=\frac{2}{5}

What are the values of x and y in the matrix equation below?
choli [55]

Answer : value of x and y in the matrix equation is:

x = -3

y = +4, -4

Step-by-step explanation :

The matrix expression is:

\left[\begin{array}{ccc}x+4\\y^2+1\end{array}\right]+\left[\begin{array}{ccc}-9x\\-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right]

First we have to add left hand side matrix.

\left[\begin{array}{ccc}(x+4)+(-9x)\\(y^2+1)+(-17)\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right]

Now we have to add left hand side terms.

\left[\begin{array}{ccc}x+4-9x\\y^2+1-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right]

\left[\begin{array}{ccc}4-8x\\y^2-16\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right]

Now we have to equating left hand side matrix to right hand matrix, we get:

\Rightarrow 4-8x=28\text{ and }y^2-16=0\\\\\Rightarrow 8x=4-28\text{ and }y^2=16\\\\\Rightarrow x=-3\text{ and }y=\pm 4

Therefore, the value of x and y in the matrix equation is -3 and +4, -4 respectively.
