Question

Can someone help me with this math homework please!

Answer 1

Answer:

h = 14

Step-by-step explanation:

We are going to use basic algebra to solve this equation.

First, let's isolate the h variables by moving -56 to the other side:

7h - 5(3h - 8) - 56 = -128

(add 56 to both sides)

7h - 5(3h - 8) = -72

Next, let's distribute the -5 to (3h - 8) by separating it from the equation then adding it back:

7h - 5(3h - 8) = -72

Separation:

-5(3h - 8) --> (-5*3h) + (-5*-8) --> (-15h) + (40)

-15h + 40

Adding it back in:

7h -15h +40 = -72

Next, let's simplify it down by adding like terms, meaning adding 7h & -15h:

7h -15h +40 = -72

(add 7h & -15h)

-8h + 40 = -72

Now we're going to move the 40 to the other side but subtracting 40:

-8h + 40 = -72

(subtract 40 to both sides)

-8h = -112

Finally, we're going to divide both sides by -8

-8h = -112 --> h = 14

The answer is h = 14

(You can double check by plugging 14 into the equation and see if it equals -128, which it does, so it's correct :-) )

Hope it helps (●'◡'●)

Answer 2

Answer: h = 14

Step-by-step explanation:

7h-5(3h-8)-56 = -128

7h -15h+40-56 = -128

or, -8h-16= -128

or, -8h = -128 + 16

or, -8h = -112

or, 8h = 112

or, h = 112/8

so, h = 14
