Given from the question 5x - 7y = 58 (first equation) y = -x + 2 (second equation)
We could use subtitution method to solve the problem. First, subtitute y with -x + 2 from second equation to first equation, and you'll find the value of x 5x - 7y = 58 5x - 7(-x + 2) = 58 5x + 7x -14 = 58 12x - 14 = 58 12x = 58 + 14 12x = 72 x = 6
Now, subtitute x with 6 to the second equation y = -x + 2 y = -6 + 2 y = -4
