Question

Use the system of equations to answer the questions.

2x + 3y = 3

y = 8 – 3x

The value of y from the second equation is substituted back into the first equation. What is the resulting equation?

What is the value of x?

What is the value of y?

Answer 1

Answer:

5,-2

Step-by-step explanation:

What's the value of X and y from the equation 2x + 5y = 0 and 3x - 4y = 23?

x+5y=0⇒6x+15y=03x−4y=23⇒6x−8y=46y=−2x=5

What is x and y in this simultaneous equation, 2x-5y=9 and 3x+4y=2?

What is x and y in this simultaneous equation, 2x+4y=1 and 3x-5y=7?

If 2x + 3y = 16, and 3x + 4y = 23, what are x and y?

If 2x-3y=0 and 3x+4y=3, what is x and y?

Is 2x+3y+4=0 and 3x+y+6=0?

Given 2x + 5y = 0 and 3x - 4y = 23

find x and y values

2x + 5y = 0 let equation (1)

3x - 4y = 23 let equation (2)

solving equation 1 and 2

(2x + 5y) = 0/ 3x - 4y = 23

multiply equation 1 by 3 and multiply equation 2 by 2

subtract equation 1 from 2

6x + 15y = 0

-(6x -8y = 46)

6x + 15y = 0

-6x +8y = -46

0x + 23y = -46

23y = -43

y = -43/23

y = -2

put y value in equation 1 i.e 2x + 5y = 0

2x + 5y = 0

2x + 5(-2) = 0

2x -10 = 0

2x = 10

x = 10/2

x = 5

. ‘ . the x and y values are (5 , -2)
