Question

Solve for x - Pre algebra

Answer 1

In this case you would set it up as
$6x + 4x + 130 = 180$
(180 represents the degree of the triangle)

Add up like terms
$10x + 130 = 180$
Subtract 130 to the other side (180-130)

$10x = 50$
Divide 10 to the other side ( 50/10)
.
$x = 5$
Hope this was clear :)

Answer 2

The sum of the measures of the interior angles of a triangle is 180 degrees.

Make the three angles add up to 180 in an equation.

6x + 130 + 4x = 180

Combine like terms.

10x + 130 = 180

Subtract 130 from both sides.

10x = 50

Divide both sides by 10.

x = 5 is your answer.
