4x-2y=-12.....I
2x-y=-6.......II

2x+6=y......iii

From eqn I
4x-2(2x-y)=-12
or,4x-4x+2y=-12
or,2y=-12
Y=-6

In eqn iii
2x+6=-6(y=-6)
or,2x=-12
X=-6

If the measure of angle ABD and DBC are a linear pair, with a measure of angle ABD = (5x+29) and measure of angle DBC=(2x+32),wh

Nonamiya [84]

Answer:

x = 17

Step-by-step explanation:

5x + 29 + 2x + 32 = 180 (linear pair means that these angles add up to 180 cos they are in a line)

7x = 119

x = 17
