Okay, take for example:
1+2=3 is the same as 1=3-2
See how we changed the place of the 2. We can do that as long we change + to - and vica versa.
Let's see your example:
6+y=-8
We move the 6 on the other side of the expression with the opposite sign (it is a rule) and we get:
y=-8-6
y=-14
The answer to your question is
86+y=99
y=99-86
y=13
Coefficients are numbers that are next to variables, multiplying them, therefore changing the value. The first 3 and 5 were next to the variables, so they are coefficients.
Answer:
(0.5, 1)
Step-by-step explanation:
The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:
Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:
The answer is thus (0.5, 1).
