5x - 7y =58

y =-x +2

Using the substitution method, replace y in the first equation with the second equation:

5x - 7(-x+2) = 58

Simplify by using the distribution property:

5x - (-7x) - 14 = 58

Simplify by combining like terms:

12x -14 = 58

Add 14 from each side of the equation:

12x = 72

Divide both sides by 12:

X = 72/12

x = 6

Now you have x, replace x in the second equation and solve for y:

y = -x +2

y = -6 +2

y = -4

X = 6, y = -4
