F(x)=2x+1
if f(x)=4, what is the value of x?

1.5

Step-by-step explanation:

F(x)=2x+1

For F(x) = 4

F(x)=2x+1 = 4

2x = 4 - 1

2x = 3

Dividing through by 2

2x/2 = 3/2

X = 3/2 = 1.5

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
