Question

Find the value of X please

Answer 1

x=12

Explanation:

we know the sum of angles of a triangle=180

6x-19+3x+7+84=180

Step 1: Simplify both sides of the equation.

6x−19+3x+7+84=180

6x+−19+3x+7+84=180

(6x+3x)+(−19+7+84)=180(Combine Like Terms)

9x+72=180

9x+72=180

Step 2: Subtract 72 from both sides.

9x+72−72=180−72

9x=108

Step 3: Divide both sides by 9.

9x/9=108/9

x=12
