Find x such that f(x) = 10 given f(x) = 4x+2

Step-by-step explanation:

We know that:

Both 4x+2 and 10 are equal to f(x). We can use substitution and set 4x+2 and 10 equal to each other.

Now, solve for x. Perform the inverse operations to isolate x on one side of the equation.

2 is being added to 4x. The inverse of addition is subtraction. Subtract 2 from both sides of the equation.

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.

For the function f(x)= 4x+2, when f(x)=20, x=2

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
