An expressions equated to another expression is called an equation
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Given that a = 5, hence:
2a + 5
substituting values:
2(5) + 5 = 10 + 5 = 15
2a + 5 = 15
The sum of twice and four times of the variable x is 2x + 4x = 6x

X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1
Answer:
<u>aₙ = aₙ₋₁ + 4</u>
Step-by-step explanation:
Finding the common difference (d) :
- d = f(2) - f(1)
- d = 7 - 3
- d = 4
Hence, the recursive formula :
We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
