Solve for x: <br>5x - 3y = 22<br> 10x - 4y = 46

Alik [6]

Answer:

x=5, y=1

Step-by-step explanation:

Isolate x for 5x-3y=22

5x-3y=22

Add 3y to both sides

5x-3y+3y=22+3y

Simplify

5x=22+3y

Divide both sides by 5

5x/5=22/5+3y/5

Simplify

x=22+3y/5

Substitute x=22+3y/5

10*22+3y/5-4y=46

Simplify 10*22+3y/5-4y

10*22+3y/5=2(3y+22)

=2(3y+22)-4y

Expand 2(3y+22)

=6y+44-4y

Simplify 6y+44-4y

=2y+44

Isolate y for 2y+44=46

2y+44=46

Subtract 44 from both sides:

2y+44-44=46-44

Simplify

2y=2

Divide both sides by 2;

2y/2=2/2

Simplify;

y=1

For x=22+3*1/5 substitute y=1

y=22+3*1/5

22+3*1=25

=25/5

Divide the numbers;25/5=5

x=5

The solutions to the system of equations are;

x=5, y=1

A box office sells balcony seats, ground-level seats, and VIP passes for shows on tour. The table shows the numbers of each type

Lana71 [14]

Answer:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Step-by-step explanation:

Let the price of one Balcony seat = $ $x$

Let the price of one Ground level seat = $ $y$

Let the price of one VIP seat = $ $z$

As per the given table:

$135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)$

Multiplying (1) with 2 and subtracting (2) from it:

$120x+290y=32100 \\12x+29y=3210..... (4)$

Subtracting (3) from (1):

$5x+15y=1600\\x+3y=320 ....... (5)$

Multiply equation (5) with 12 and subtracting (4) from it:

$7y=630\\\Rightarrow y =\bold{90}$

By equation (5), putting value of $y$ :

$x=\bold{50}$

By equation (1), putting the values of $x, y:$

$135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}$

Therefore, the answers are:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180
