Answer:
x = 11, y = -1/2.
In parentheses the answer is (11, -1/2).
Step-by-step explanation:
x + 4y = 9
x - 2y = 12 Subtract to eliminate the x:
6y = -3
y = -1/2
Substituting in the first equation:
x + 4(-1/2) = 9
x - 2 = 9
x = 11.
Check the results in equation 2:
11 - 2(-1/2)
= 11 + 1
= 12
So it checks out ok.
God bless you too.
Answer:
x = 11, y=-½
Step-by-step explanation:
Simultaneous equations - subtract the first equation from the second.
x + 4y = 9
-(x - 2y = 12)
6y = -3
y = -½
Substitute y
x + 4(-½) = 9
x + -2 = 9
x = 11
