Good morning ☕️
Step-by-step explanation:
11+y is an expression that contains a variable ‘y’
then its value depends on ’y’
examples :
if y = 0 → 11+y = 11+0 = 11
if y = 1 → 11+y = 11+1 = 12
if y = 2 → 11+y = 11+2 = 13
and so on.

Answer:
True
Step-by-step explanation:
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Substitution method can be applied in four steps
Step 1:
Solve one of the equations for either <span>x = </span>or y = .
Step 2:
Substitute the solution from step 1 into the other equation.
Step 3:
Solve this new equation.
Step 4:
Solve for the second variable.
hope this helps you!
