Note:

Your function is a little ambiguous. I think you may have tried to write your function such as:

I am assuming your function as:

f(x) = 4x + 3

Answer:

The value of f(3) = 15

Step-by-step explanation:

Given

Assuming the function is

f(x) = 4x + 3

To determine

The value of f(3)

The value of f(3) can be determined by substituting x = 3 in the function

f(x) = 4x + 3

substitue x = 3 in the function

f(3) = 4(3) + 3

f(3) = 12 + 3

f(3) = 15

Therefore, the value of f(3) = 15

I need to know the solution to this

Alex73 [517]

There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate

Look at equation 1, $-2x+y=10$ this can quite easily be manipulated to show $y=10+2x$ .

Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one $4x-y=-14 \Rightarrow 4x-(10+2x)=-14$ which can then be solved for x since there is only one variable $4x-10-2x=-14 \Rightarrow 2x=-4 \Rightarrow x=-2$ and then with our x solution we can work out our y solution by using the equation we manipulated $y=10+2x = 10+(2 \times -2) = 10-4=6$ .

So the solution to these equations is x=-2 when y=6
