Question

Solve the following system of equations:
x - 2y = 14

x + 3y = 9


A) (1, 12)
B) (-1, -12)
C) (12, -1)
D) (12, 1)

Answer 1

We want to cancel out each varible to find the value
x - 2y = 14
x + 3y = 9
A negative - a positvive results in a 0
so whats the opposite of 1 ?

Answer 2

-1

Answer 3

Good
-1(x - 2y = 14)
x + 3y = 9

\[\huge~\rm~-1(x - 2y = 14) \]
distribute

Answer 4

how would I do that

Answer 5

-1 times x = ?
-1 times -2 =?
-1 times 14=?
