Answer:
x = 
Step-by-step explanation:
12-5x-4kx=y
1. Subtract 12 from both sides.
2.Distrubutive property (factor) a(b+c)=ab+ac
x(-5-4k)=y-12
x = 
= 
Answer:
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
Step 1: Cross-multiply
Step 2: Divide both sides by 15
Hope it helps:)
I think its x=27 im not sure sorry if its wrong!
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
