Answer:
c
Step-by-step explanation:
First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18
4x-12.
4x/4-12/4. So x=3
The fours cancelled out
7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out
Answer:
142,180 and 10 and 23 and that it
3z - 12 = 63
+ 12 +12
3z = 75
z = 25
x + 63 = 180
- 63 - 63
x = 117°
