Solve using substituion -5x + y = -2 -3x + 6y = -12

Step-by-step explanation:

-5x + y = -2………… Equation 1

-3x + 6y = -12 ………… Equation 2

Using substitution

Make y the subject in equation 1 and substitute it into equation 2 and solve for x

That's

y = 5x - 2

We have

- 3x + 6( 5x - 2) = - 12

- 3x + 30x - 12 = - 12

27x = - 12 + 12

27x = 0

Divide both sides by 27

x = 0

Substitute x = 0 into y = 5x - 2

We have

y = 5(0) - 2

y = - 2

So the solutions are

Hope this helps you

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.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
