Two equations are given below:

1 answer:

3 0

You can fill the second in in the first to get an equation with only b:

(b-2) - 3b = 22 =>

-4b-2 = 22 =>

-4b = 24

b = -6

a = -6-2 = -8

So (-8,-6) is the answer.

Answer:

Fourth Quadrant

Step-by-step explanation:

a>0 = a is a positive number = +y

b<0 = b is a negative number = -x

[-b,-a] = [-(-x), -(+y)] = [x, -y]

[positive, negative] is on the fourth quadrant

Solve the system of equations 4x+5y=-1 and -5x-8y=10 by combining the equations.

Flura [38]

The solutions to the given system of equations are x = 6 and y = -5

<h3>Simultaneous linear equations</h3>

From the question, we are to solve the given system of equations

The given system of equation is

4x+5y=-1

-5x-8y=10

Multiply the <u>first equation</u> by 5 and the <u>second equation</u> by 4

5× (4x+5y=-1)

4× (-5x-8y=10)

20x + 25y = -5

-20x - 32y = 40

------------------------

0x + (-7y) = 35

-7y = 35

y = 35/-7

y = -5

Substitute the value of y into the first equation to find x

4x + 5y = -1

4x + 5(-5) = -1

4x -25 = -1

4x = -1 +25

4x = 24

x = 24/4

x = 6

Hence, the solutions to the given system of equations are x = 6 and y = -5
