Use addition to solve the linear system of equations.

y = 2x - 5

3x + 3 = 7

(2, - 1)

(2, 1)

(-8, - 21)

(-1.6, - 8.2)

(-8, - 21)

Step-by-step explanation:

Given the two equations ...

y = 2x - 5 3x + 3 = y

you can solve them by adding the first equation to the second.

... (y) + (3x+3) = (2x-5) + (y)

... y + 3x + 3 = 2x - 5 + y

Adding - y - 2x - 3 to both sides of the equation gives ...

... x = - 8

Putting this value in the first equation gives ...

... y = 2 (-8) - 5 = - 21
