Solve the system using elimination.
2x + 3y = -2
3х – 6у = 18

x = 2 and y = -2

Step-by-step explanation:

We must first eliminate the y-variable:

2x + 3y = -2

3x - 6y = 18

4x + 6y = -4

3x - 6y = 18

7x = 14

x = 2

Since we know x=2, we plug that back into one of the original equations to find y:

2x + 3y = -2

2(2) + 3y = -2

4 + 3y = -2

3y = -6

y = -2

Therefore, x = 2 and y = -2

Step-by-step explanation:

2x+3y= -2 1

3x - 6y = 18 2

Multiply both Sides of equation 1 by 2

4x + 6y = -4

3x - 6y = 18

(add Like terms)

7x = 14 (devide both Sides by 7)

.°. x = 2

Substitude x = 2 into equation 1

.°. 2(2) + 3y = -2 (multiple the digit)

4 + 3y = -2 (Move 4 to the right and change it's sign)

3y = -6 (devide both side by 3)

y = -2

Final answers x = 2 ; y = -2

{2 ; -2}

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
