Answer:

x=−3x−7whatish(−4)

Step 1: Flip the equation.

28ah2istw−3x=x

Step 2: Add 3x to both sides.

28ah2istw−3x+3x=x+3x

28ah2istw=4x

Step 3: Divide both sides by 28h^2istw.

28ah2istw

28h2istw

=

Answer:

x = -1 when h(x) = -4

Step-by-step explanation:

Solve for x when h(x)= -4

h(x) = -3x - 7

-3x - 7 = -4

     +7    +7

-3x = 3

divide -3 by 3

-3x/3 = 3/-3

x = -1

You can check this by plugging the -1 into x

-3x - 7

-3(-1) - 7

3 - 7 = -4
