Solve the given via substitution method

2x + y = 8

3x - 2y = -2

Solution

Solve the first equation for y

y = 8 - 2x

Now substitute this value of y into the second equation and then solve for x

3x - 2y = -2

3x - 2 (8-2x) = -2

x = 2

Now substitute this value of x into either the first or the second original equation and then solve for y

2x + y = 8

(2) (2) + y = 8

y = 4
