(x+2y=-2
5x – 3y = 29
how can I solve this?

  (x, y) = (4, -3)

Step-by-step explanation:

I like a graphing calculator for most 1- and 2-variable problems.

Here, it looks convenient to use substitution: solve the first equation for x and use that in the second equation.

  x = -2 -2y

  5(-2 -2y) -3y = 29 . . . . substitute for x

  -10 -10y -3y  = 29 . . . . eliminate parentheses

  -13y = 39 . . . . . . . . . . . collect terms, add 10

  y = -3 . . . . . . . . . . . . . . .divide by -13

  x = -2 -2(-3) = 4 . . . . . . use the equation for x to find x

(x, y) = (4, -3) . . . . the solution

it is b)

hope this : )
