6q-7=2q+29 I don't know how to do this, help please.

Tems11 [23]

The first thing you should do is to add -2q on both sides of the equation and then add +7 on both sides so you will have:
6q - 2q = 29 +7
4q = 36 so q is equal to 36/4 or 9 :)))

Answer:

$9$

Step-by-step explanation:

As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.

Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; ( $a^2 + b^2 = c^2$ ), where ( $a$ ) and ( $b$ ) are the legs of the right triangle, or the sides adjacent to the right angle. ( $c$ ) is the hypotenuse or the side opposite the right angle.
