Question

11. Solve 5(2x – 3) = x – 15 + 9x for x.

Answer 1

Answer:

$\boxed{\bold{True \ For \ All \ x}}$

Explanation:

[ Step One ] Group Like Terms

$\bold{5\left(2x-3\right)=x+9x-15}$

[ Step Two ] Combine Similar Elements: $\bold{x+9x=10x}$

$\bold{5\left(2x-3\right)=10x-15}$

[ Step Three ] Expand $\bold{5\left(2x-3\right): \ 10x-15}$

$\bold{10x-15=10x-15}$

[ Step Four ] Add 15 To Both Sides

$\bold{10x-15+15=10x-15+15}$

[ Step Five ] Simplify

$\bold{10x=10x}$

[ Step Six ] Subtract 10x From Both Sides

$\bold{10x-10x=10x-10x}$

[ Step Seven ] Simplify

$\bold{0=0}$

[ $\boxed{\bold{Final \ Answer}}$ ]

➤ $\bold{Both \ Sides \ Are \ Equal, \ True \ For \ All \ x}$

$\boxed{\bold{Mordancy}}$
