Question

for f(x)=4x+2, what value of x makes f(x)=-14

Answer 1

Hey there,

f(x) = 4x + 2

what value of x makes f(x) = -14?

• Answer :

x = -4 ✅

• Explanations:

f(x) = 4x + 2

>> We want f(x) to be equal to -14:

4x + 2 = -14

>> Substract 2 from both sides :

4x + 2 - 2 = -14 - 2

4x = -16

>> Divide both sides by 4:

4x/4 = -16/4

x = -4

Have a good day ;)

Answer 2

Answer:

x = -4

Step-by-step explanation:

Given:

• f(x) = 4x + 2

If the value of f(x) is -14,

⇒ 4x + 2 = -14                                                                       [f(x) = 4x - 2 and -14]

To simplify the equation, we need to isolate the variable completely. Start out by subtracting 2 both sides. This will isolate "x" and the cooeficient of x.

• ⇒ 4x = -14 - 2
• ⇒ 4x = -16

Then, divide 4 both sides to isolate the cooeficient of x on one side and a constant on the other side. The constant will be the value of x.

• ⇒ 4x/4 = -16/4
• ⇒ x = -4

Thus, -4 is the value of x that makes f(x) equivalent to -14
