4. Use substitution to solve the following system of equations. What is the value of y? 3x + 4y = 36
2x - y = 2
Oy-6
Oy=4
Oy=-6
Oy=.4

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
