Solve the following system:
{x = y + 1 | (equation 1)
{4 x - 5 y = -9 | (equation 2)

Express the system in standard form:
{x - y = 1 | (equation 1)
{4 x - 5 y = -9 | (equation 2)

Swap equation 1 with equation 2:
{4 x - 5 y = -9 | (equation 1)
{x - y = 1 | (equation 2)
Subtract 1/4 × (equation 1) from equation 2:
{4 x - 5 y = -9 | (equation 1)
{0 x+y/4 = 13/4 | (equation 2)

Multiply equation 2 by 4:
{4 x - 5 y = -9 | (equation 1)
{0 x+y = 13 | (equation 2)

Add 5 × (equation 2) to equation 1:
{4 x+0 y = 56 | (equation 1)
{0 x+y = 13 | (equation 2)

Divide equation 1 by 4:
{x+0 y = 14 | (equation 1)
{0 x+y = 13 | (equation 2)

Collect results:
Answer: {x = 14
               {y = 13

Jason builds doghouses for a pet store. Each doghouse is a wooden structure with a rectangular base that has an area of 21 squar
krok68 [10]

The equation that can be used to determine the dimensions of the base of the doghouse is x² + 4x = 21

<h3> What is the equation?</h3>

A quadratic equation is an equation that usually has a single variable and it is raised to the power of 2.

Area of a rectangle = length x width

  • width = x
  • length = 4 + x

x (4 + x) = 21

x² + 4x = 21

Muriel says she has written a system of two linear equations that has an infinite number of solutions. One of the equations of t
erastova [34]
Infinite number of solutions...means it will be the same line.
you have probably heard about equivalent fractions like 1/2 = 2/4...and if u reduce 2/4, it equals 1/2. Well...there are also equivalent equations. They can also be reduced.

3y = 2x - 9 cant be reduced, but u can make an equivalent equation by multiplying it all by a number.Any number.

lets try 2...
2(3y = 2x - 9) =
 6y = 4x - 18...this is an equivalent equation....the same line..infinite solutions.Notice that u can reduce it by dividing everything by 2 which would equal 3y = 2x - 9....so u see, it is like equivalent fractions....kind of...lol

or multiply it by 3
3(3y = 2x - 9) =
9y = 6x - 27....this is also equivalent.....so this is an answer as well

and u can multiply it by 4 and get another equivalent equation..or 5, or 6....and so on...

make any sense ?? Just remember, to get the result of infinite solutions, the equations have to be equivalent
