Solve the simultaneous equation:<br> 5 x + 2 y = 25 <br> 5 x − y = 10
Liono4ka [1.6K]

Answer:

(x, y) = (3, 5)

Step-by-step explanation:

5x+2y=25\\5x-y=10

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

5x+2y=25\\\\2(5x-y=10)\\10x-2y=20

Add from top to bottom:

\rightarrow (5x+10x)+(2y-2y)=25+20\\\rightarrow 15x=45\\\rightarrow x=3

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

\rightarrow 5x-y=10\\\rightarrow 5(3)-y=10\\\rightarrow 15-y=10\\\rightarrow -y=-5\\\rightarrow y=5

(x, y) = (3, 5)

The product of a linear monomial and a linear binomial is a ​
oksian1 [2.3K]

Answer:

The product of a linear monomial and a linear binomial is a second degree binomial

Step-by-step explanation:

Examples of linear monomials are:

2x

2a

y

Examples of linear binomials are:

2x+y

x-y

3a+b

x+1

When we take the product of a linear monomial and a linear bbinomial we obtain:

2a(3a+b)=6a²+2ab

y(x+1)=xy+y

y(x-y)=xy-y²

These are all second degree binomials.
