Find 3 solutions that satisfy the equation -5x=10+2y

Mathematics
1 answer:
Dominik [7]2 years ago
3 0

Answer:

(2, -10)

(4, -15)

(6, -20)

Step-by-step explanation:

First you should simplify the equation.

-5x=<u>10</u>+2y

-5x-10=<u>2y</u>

<u>-2.5x-5=y</u>

Then put in any number in for x. since we have a decimal I'll make the numbers I put in even the keep the solution whole numbers.

<u>Putting in 2 gives you -10 so (2, -10) is a solution.</u>

<u>Putting in 4 gives you -15 so (4, -15) is a solution.</u>

<u>Putting in 6 gives you -20 so (6, -20) is a solution.</u>

The answer is the last one. The main goal is to get the initial velocity alone, and by solving that treat it like your solving an equation. I showed the process of how I got the answer attached. But if you want me to explain it, I am glad to do it.

Examine the system of equations. −5x 5y = 40 4x 3y = 24 What is the solution? ( , ).
Elden [556K]

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

The solution of the equation is (0,8)

<h3>What is system of equation?</h3>

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Given information-

The first equitation given in the problem is,

-5x+5y = 40

Divide both side of the above equation with 5 as,

\dfrac{(-5x+5y )}{5}= \dfrac{40}{5}\\-x+y=8\\y=8+x          .......1

Let the above equation as equitation 1.

The first equitation given in the problem is,

4x+ 3y = 24

Put the value of <em>y</em> form the equation 1 in the above equation as,

\begin{aligned}4x+ 3(x+8) &= 24\\4x+ 3x+24 &= 24\\4x+ 3x &= 24-24\\7x&=0\\x&=0\\\end

Put the value of <em>x</em> in the equation one as,

y=8+0\\y=8          

Thus the solution of the equation is (0,8)
