3+x=2-3x a) 0 b) 1 c) infinitely many

The answer is A) 0

3 + x - 2 = 3x
x + 1 = -3x
1 = -3x - x
1 = -4x
x = -1/4.

B) 1

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
