Answer:
r=7
Step-by-step explanation:
-84+15r=3r
Subtract 15r from each side
-84+15r-15r=3r-15r
-84 = -12r
Divide each side by -12
-84/-12 = -12r/-12
7 = r
Hello!
Answer:
1. first u want to distribute the 3
3(n+4)+2
3n+12+2
Then add 12 and 2
3n+14
2. again, distribute
5(w+2)+3w-4
5w+10+3w-4
subtract
5w+10-4+3w-4-4
combine like terms
5w+3w+6+3w+3w
8w+6
3. distribute
3(w-2y)+w+4
3w-6y+w+4
Combine like terms
4w-6y+4
these are the first 3. if this is not what you wanted pls reach out! Hop this helps! :)
Answer:
2+2 is 22 ahahahhahaha just kidding
Hey bae use math-way it will definitely help
To find the value of y, you need to plug a value into the x variable, in this case -8.
4x + 9y = -14 Substitute -8 for x
4 (-8) + 9y = -14 Multiply
-32 + 9y = -14 Start isolating the variable by adding 32 to both sides
9y = 18 Divide both sides by 9
y = 2
When x = -8, y = 2
