X(a-b)=b(c-x)<br>make x the subject of the formular <br>pls help meee

dezoksy [38]

Answer:

$X(a - b) = b (c - x) : x = - -\frac{X\left(a-b\right)-bc}{b};\quad \:b\ne \:0$

Step-by-step explanation:

$X\left(a-b\right)=b\left(c-x\right)$

Switch sides:

$b\left(c-x\right)=X\left(a-b\right)$

Divide both sides by; $\:b\ne \:0$

$\frac{b\left(c-x\right)}{b}=\frac{X\left(a-b\right)}{b};\quad \:b\ne \:0$

Simplify:

$\frac{b\left(c-x\right)}{b}=\frac{X\left(a-b\right)}{b};\quad \:b\ne \:0$

Subtract $c$ from both sides:

$c-x-c=\frac{X\left(a-b\right)}{b}-c;\quad \:b\ne \:0$

Simplify:

$-x=\frac{X\left(a-b\right)}{b}-c;\quad \:b\ne \:0$

Divide both sides by $-1;\quad \:b\ne \:0$ :

$\frac{-x}{-1}=\frac{\frac{X\left(a-b\right)}{b}}{-1}-\frac{c}{-1};\quad \:b\ne \:0$

Simplify:

$x=-\frac{X\left(a-b\right)-bc}{b};\quad \:b\ne \:0$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you. Have a good day! =)

How many solutions does the system have?

umka21 [38]

One solution

<h2>Explanation:</h2>

For a system of linear equations in two variables, we could have three possible cases:

<h3>Case 1. No solution.</h3>

This happens when the lines are parallel and have different y-intercepts.

<h3>Case 2. One solution.</h3>

This happens when the lines intersect at a single point.

<h3>Case 1. Infinitely many solutions</h3>

This happens when the lines are basically the same having the same slope and y-intercept.

So, let's rewrite our lines in Slope-intercept form $y=mx+b$ :

$Line \ 1: \\ \\ 4x-2y = 8 \\ \\ 2y=4x-8 \\ \\ y=\frac{4}{2}x-\frac{8}{2} \\ \\ y=2x-4 \\ \\ \\ Line \ 2: \\ \\ 2x + y = 2 \\ \\ y=-2x+2$

As you can see, they have different slopes and y-intercepts. So they will intersect at a single point which is the solution of the system. By using graphing tool we get that this point is (1.5, -1) as indicated in the figure below.

5. Max and Evie are comparing the number of ride tickets they have for an amusement park. They notice that Evie has 4 less than

Anestetic [448]

Answer:

4n - 4

Step-by-step explanation:

3n-4 = the amount of tickets Evie has

n = the amount of tickets Mark has

3n - 4 + n = 4n - 4
