(2, 6)
Step-by-step explanation:
if you meant for both of the y to be the same then this should be right
Answer:
(2,6)
Step-by-step explanation:
*this is actually elimination*
1st- Turn both of them into standard form.
y=9x-12 ---> 9x-y=12
y=3x --> 3x-y=0
--
Multiply 9x-y=12 by -1
-9x+y=-12
3x-y=0
-6x=-12
divide by 6
x=2
--
Plug 2 into the first equation
9(2)-y=12
18-y=12
Cancel out 18 by subtracting -18 to both sides
-y=-6
divide by -1
y= 6

Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
Subtract-3/4 from both sides
Simplify
For the 11 the first one is x = 4y and for the 2 one it will be x=−6−2y
Supplementary angles add up to 180 degrees.
so if one angle is 60 degrees, then the other angle is (180 - 60) = 120
