Answer: x is 3 and y is 2

Step-by-step explanation:

JulsSmile [24]2 years ago

Answer:

The solution is x = 3, y = 2.

Step-by-step explanation:

4x + 6y = 24

15x – 6y = 33    Add these 2 equations:

19x = 57

x = 57/19

x = 3.          Now Substitute for x in the original equation:

2(3) + 3y = 12

3y = 12 - 6

2y = 6

y = 2.

4x + 3y = 22<br> 5x - 4y = 43<br> Simultaneous Equation
oksano4ka [1.4K]

Answer:

x = 7

y = -2

Step-by-step explanation:

4x + 3y = 22  ---------------------(I)

5x - 4y = 43 ---------------------(II)

Multiply(I) by 4 and equation (II) by 3. And then add the equations

(I) * 4            16x + 12y = 88

(II) *3            <u>15x  - 12y = 129</u>   {Add & thus y will be eliminated}

                    31x         = 217

x = 217/31  

x = 7

Plug in the value of x in equation (I)

4*7 + 3y = 22

28 + 3y = 22

       3y = 22 - 28

       3y = -6

         y = -6/3

y = -2

X+1.5 (x-3)=5/2 solve pls help me it's an immediate thing I will give 20 p for it
Yuki888 [10]
X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5

An empty shipping box weighs 250 grams. The box is then filled with T-shirts. Each T-shirt weighs 132.5 grams.  The equation  re
just olya [345]

Answer:

<u>Equation:</u>

<u>250 + 132.5y = x</u>

<u>Solution for solving for x:</u>

<u>x = 250 + 132.5y</u>

<u>Solution for solving for y:</u>

<u>y = (x - 250)/132.5</u>

<u>In this situation, the solutions mean that the equation is linear or first grade because the solutions can be calculated in any of the following four forms:</u>

<u>1. Adding the same number to both sides</u>

<u>2. Subtracting the same number from both sides </u>

<u>3. Multiplying both sides by the same number </u>

<u>4. Dividing both sides by the same number</u>

Completing the question and statement correctly:

The equation  represents the relationship between the quantities in this situation, where x is the weight, in grams, of the filled box and y the number of shirts in the box.

Step-by-step explanation:

1. Let's review all the information provided to us to answer the question correctly:

Weight of an empty box = 250 grams

Weight of each T-shirt = 132.5 grams

2. Name two possible solutions to the equation that represent the relationship between the quantities in this situation, where x  is the weight, in grams, of the filled box and y the number of shirts in the box. What do the solutions mean in this situation?

x = weight, in grams, of the filled box

y = number of shirts in the box

Equation:

250 + 132.5y = x

Solution for solving for x:

x = 250 + 132.5y

Solution for solving for y:

y = (x - 250)/132.5

In this situation, the solutions mean that the equation is linear or first grade because the solutions can be calculated in any of the following four forms:

1. Adding the same number to both sides

2. Subtracting the same number from both sides

3. Multiplying both sides by the same number

4. Dividing both sides by the same number
