A semicolon is used to separate variables from parameters. that we are defining a function of the parameters that returns a function of the variables.
A/b=c
times both sides by b
A=bc
divide both sides by c
A/c=b
b=A/c
Answer:
(-2, 7); (See attachment)
Step-by-step explanation:
x + 2y = 12
7x + 2y = 0
x + 2y = 12
x = -2y + 12
Solve for y:
7x + 2y = 0
7 (-2y + 12) + 2y = 0
-12y + 84 = 0
-12y = -84
y = 7
Solve for x:
x = -2y + 12
x = -2 (7) + 12
x = -2
x = -2, y = 7
