Solve the system by substitution

kramer

Answer:

The solution to the system of equations be:

$x=3,\:y=-2$

Step-by-step explanation:

Given the system of equations

4x-2y = 16

y = -5x+13

Solving the system of equations using the substitution method

$\begin{bmatrix}4x-2y=16\\ y=-5x+13\end{bmatrix}$

Substitute y = -5x+13 in 4x-2y = 16

$4x-2\left(-5x+13\right)=16$

$4x+10x-26 = 16$

$14x-26 = 16$

Now isolate x for $14x-26 = 16$

$14x-26=16$

Add 26 to both sides

$14x-26+26=16+26$

Simplify

$14x=42$

Divide both sides by 14

$\frac{14x}{14}=\frac{42}{14}$

Simplify

$x=3$

For y = -5x+13

Substitute x = 3

$y=-5\cdot \:3+13$

Simplify

$y=-2$

Therefore, the solution to the system of equations be:

$x=3,\:y=-2$

At Long Bridge middle school 240 student said that they are an only child which is 48% at school student enrollment how many stu

Olegator [25]

It should be 115.

If you set it up as a ratio format using the percentage version of the equation, you'll set it up like this:

x/240 to 48/100

Then multiply 48 by 240 and divide by 100 to receive the x or 48% of 240.

Hope this helps!
