How do you solve #12h = 4( 2h - 5)#?

Answer 1

Savannah Anderson

h = -5

the following: remove brackets: 12h = 8h - 20 subtract 8h from both sides: 4h = -20 divide by 4: h = -5

To solve the equation ( 12h = 4(2h - 5) ), follow these steps:

Distribute the ( 4 ) on the right side of the equation: [ 12h = 8h - 20 ]
Subtract ( 8h ) from both sides to isolate ( h ) on one side of the equation: [ 12h - 8h = -20 ] [ 4h = -20 ]
Divide both sides by ( 4 ) to solve for ( h ): [ \frac{4h}{4} = \frac{-20}{4} ] [ h = -5 ]

So, the solution to the equation ( 12h = 4(2h - 5) ) is ( h = -5 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
