Using the substitution method, Nelly is solving the following system of equations algebraically. 2x + y = 11
x-3y = -5

What equivalent equation could Nelly use?
1) Зу - 5 - Зу = -5
2) -3y - 5 - 3y = -5
3) 2(3y - 5) + y = 11
4) 2(-3y – 5) + y = 11

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse
