Find h(7) if h(x)=-7x-3

h(7) = -52

Step-by-step explanation:

To get our answer, we must first set up the equation by plugging the value of 7 into x.

h(7) = -7(7) - 3

Following the order of operations, we multiply the number inside the parentheses by the number outside of it first.

-7 × 7 = -49

That leaves us with h(7) = -49 - 3

Now we subtract what's left to find our answer.

-49 - 3 = -52

h(7) = -52

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
