What are the solutions to the system of equations? y = 2x² + 6x - 10 \ y = y = -x + 5

Akimi4 [234]

Answer:

x= 1.5, y= 3.5

or x= -5, y= 10

Step-by-step explanation:

Let's solve by substitution.

Label the two equations:

y= 2x² +6x -10 -----(1)

y= -x +5 -----(2)

Substitute (2) into (1):

2x² +6x -10= -x +5

2x² +6x +x -10 -5= 0

Simplify:

2x² +7x -15= 0

Factorise:

(2x -3)(x +5)= 0

2x -3= 0 or x +5= 0

2x= 3 or x= -5

x= 1.5

Now that we have found the value of x, we can find the value of y through substitution.

Substitute into (2):

y= -1.5 +5 or y= -(-5) +5

y= 3.5 or y= 10

2x - 3y = 2, 4x + 7y = -9.

kodGreya [7K]

Step-by-step explanation:if you like it press thank you ❤❤❤

2x-3y=2 4x+7y= -9

2x=2+3y

2x=2+3y

2 2

x=2+3y 4(2+3y) + 7y= -9

 2 2

8+12y + 7y= -9

2

8+12y+14y = -9

2

8+12y+14y= -18

26y= -26

26y = -26

26 26

y= -1

4x+7(-1)= -9

4x+(-7)= -9

4x-7= -9

4x = -2 now lets check,4(-1) + 7(-1)= -9 or 2(-1)-3(-1)=2

4 4 2 2

x=-1 -4 +(-7) = -9 -1-(-3)=2

2 2 -1+3=2

-2-7= -9 2=2

-9= -9

so the answer is x= -1 and y= -1
