Answer:
Step-by-step explanation:
In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
97+x=27+64
x=27+64-97
x=-6
(Hopefully this is correct)
Answer:
3/25
Step-by-step explanation:
This is because when you divide 12/100 and simplify. All you need to focus on is that there are 100 tiles and twelve of them are with the letter E the simplify from there. all the other information is just there to distract you.
2x - 3y = -1
y =x -1
2x - 3y = -1
2x - 3(x-1)=-1
2x-3x + 3 = -1
-x + 3 = -1
-x = -3 -1
-x = -4
x= 4
Answer: x = 1
Step-by-step explanation:
2log(x+1) - log (x+3) = log 1
log(x+1)^2 - log (x+3) = log 1
log [(x+1)^2 / (x+3)] = log 1
(x+1)^2 / (x+3) = 0
(x+1)^2 = 0
x = 1 or x = -1 (rejected, as log0 does not exist)
