Answer:

x = 8/3 or 2 2/3

Step-by-step explanation:

if angles A and B are complementary then their sum is 90 degrees

we can write the following equation to find 'x':

3x + 4 = 6x - 4

subtract '3x' from each side:

4 = 3x - 4

add 4 to each side:

8 = 3x

divide each side by 3:

8/3 = x

or x = 2 2/3
