Question

x+3y=0
11x-2y=35

Answer 1

from the first equation:
x + 3y = 0
subtract 3y from both sides and get:
x = -3y

now plug x into the second equation :

11 * (-3y) -2y = 35
-33y - 2y = 35
-35y = 35
y=-1

now plug y back into x=-3y and get
x = -3 * (-1) = 3

Answer 2

its for multiplication and Addition elimination and I am so clueless

Answer 3

ok i used substitution ..
multiply the first equation by -11 and get:
-11x-33y = 0
add it to the second and get :
-33y-2y = 35
-35y = 35
y = -1
plug it back into the first and get
x = 3
