Answer:
3x - 4 = 32
Step-by-step explanation:
We solve for x to find the number (knowing that x is the unknown number).
3x - 4 = 32
3x = 32 + 4
3x = 36
x/3 = 36/3
x = 12
Answer:
x = 19
Step-by-step explanation:
The two angles with measures are supplementary.
6x + 9 + 4x - 19 = 180
10x - 10 = 180
10x = 190
x = 19
