Question

What is the answer for x? (3x-3)° [6(x-10)]

Answer 1

Answer:

x = 19

Step-by-step explanation:

The angles are vertical angles which means they are equal

3x-3 = 6(x-10)

Distribute

3x-3 = 6x-60

Subtract 3x from each side

3x-3 -3x = 6x-60-3x

-3 =3x-60

Add 60 to each side

-3+60 =3x-60+60

57 = 3x

Divide by 3

57/3 = 3x/3

19 =x

Answer 2

Answer:

$\boxed{x=19}$

Step-by-step explanation:

The angles are vertically opposite to one another.

Vertically opposite angles are equal in size.

Put up an equation and solve for $x$.

$3x-3=6(x-10)$

Expand brackets.

$3x-3=6x-60$

Add -6x and 3 on both sides.

$-3x=-57$

Divide both sides by -3.

$x=19$
