The x=16 because you gotta subtract x one one side to make it a simple two step equation then to simplify x from 5x divide by 5 on both sides
Answer:
In linear expresiion 3 is the coefficient
X will be the variable and -15 will be the constant term.
Pi radians = 180 degrees

The answer is: 3.491 radians to 3 dp.
From the graph, identify the x=-2 point on x axis,
(is it 2 units to left of origin.)
now, imagine a vertical line through it.
This vertical line intersects the given line at which point?
The y co-ordinate of this point is your answer.
From the given graph,
the vertical line intersects at (-2,3)
so y= 3 it is :)
