Answer:

Required Answer:-

Given:

5x - 3y = 2

3x - 2y = 4

To Find:

The values of x and y.

Solution:

We have,

→ 5x - 3y = 2 – (i)  

→ 3x - 2y = 4 – (ii)  

Multiplying equation (i) by 2, we get,  

→ 10x - 6y = 4 – (iii)

Multiplying equation (ii) by 3, we get,  

→ 9x - 6y = 12 – (iv)

Subtracting (iii) from (iv), we get,  

→ -x = 8  

→ x = -8  

Now, from (i),

→ 5 × (-8) - 3y = 2

→ -40 - 2 = 3y

→ -42 = 3y

→ y = -14  

So,  

→ (x, y) = (-8, -14)

Answer:

(x, y) = (-8, -14)

Can you help me with number 9 please i dont get it
irinina [24]

Answer:

So the question is asking you to write an expression which can be defined as a mathematical equation that contains two numbers (usually a <u>variable</u> represented by a letter from the english alphabet and a <u>constant</u> like 1, 2, 15, 73, or 10) and at the very least, one operation. So we are instructed to write an expression WITH an exponent. Examples of exponents would be squaring or cubing a number: 2² or 5³

With this kind of problem its more of a guess and check to try and see which numbers would make the equation true/equal to 24.

Here is an example of what I would put down:

24 = 3x³

24/3 = x³

8 = x³

2 x 2 x 2 = x³

2 = x

Check by plugging our x-value in:

24 = 3 x 2³

24 = 3(8)

24 = 24
