6x-3y=3
-2x+6y=14.
First step is multiply the top equation by 2, so you have
12x-6y=6
-2x+6y=14
-6y and +6y cancel each other out, so if you simplify, you have
10x=20, which is then solved by dividing each side by 10, and getting x=2.
Now plug x=2 into one of the equations (I chose the first)
6(2)-3y=3
12-3y=3
-3y=-9, divide each side by -3 and get y=3.
so your point is (2,3)
Answer:
The first one is 12
second one is 1
third one is 23
last one 5
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Rational numbers have an ending decimal expansion. If you put the other numbers into a calculator you will se that there is just more numbers after the decimal point
5x+15=90
5x= 75
X=15
Because it’s complementary
