Step-by-step explanation:
step 1. 15^18/15^3
step 2. 15^18*15^-3
step 3. 15^(18 - 3)
step 4. 15^15
The anawer to your question is 3/6, and simplified as 1/2.
X - the number
3x - 7 = -4 |add 7 to both sides
3x = 3 |divide both sides by 3
x = 1
Answer:
11-2x=x+2
-3x=9
x=-3
Step-by-step explanation:
y=11-2x
y=x+2
So we use the first equation to plug in for the second equation.
Then we solve for x and get the answer. Hope this helps. Thank you.
