15x-10=20
+10 +10
15x=30
\15 /15
x=2
you add 10 to both -10 (they cancek eachother out) and 20 (equals 30)
Then you divide 30 by 15 (equals 2) and 15 by 15 (they cancel eachother out)
Then you get x=2
Answer: p = -4
Step-by-step explanation:
9-4(2p-1) = 45
9-8p+4 = 45
13-8p = 45
-8p = 45 - 13
-8p = 32
p = -(32/8)
p = -4
