Answer:
Step-by-step explanation:
8x - 2y = 6
-8x + 4y = 12
2y = 18
y = 9
8x - 18 = 6
8x = 24
x = 3
(9, 3)
Answer:
i would say a. or c. because im in tenth grade civics right now and those sound like more political problems than the other ones.
3(2m+12) -4m = 20 -3(3m+5)
Step 1. Distribute 3 to (2m+12) and -3 to (3m+5)
Distribution property:
When you are distributing, you multiply the outside number by the numbers inside. For example,
-1(4-2)
-1 times 4, -1 times -2
-4, 2 (negative times negative =positive)
Then you would get
-4+2. You do not distribute with multiplication and division. So then we would do this with our numbers.
6m+36 -4m = 20 -9m-15
______
Step 2. Simplify by adding like terms.
Like terms:
Terms are separated by operation symbols (+,-,*,➗). Like terms are terms with the same variable next to it. 5a and 6a are like terms. Terms with no variables at all are also like terms. 5 and 6 are like terms. 8a and 7 are not like terms. 9a and 9b are not like terms.
6m+-4m= 2m. 20+(-15)=5
_____
2m+36=5-9m
Step 3. Add 9m to both sides
11m+36=5
____
Step 4. Subtract 36 from both sides
11m=-31
____
Step 5. Divide by 11
m=-31/11
If you can please provide brainliest. I took 30 minutes doing this.
Answer:
3 4/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
we will use first the distributive property and multiply
45+ 5a<110
subtract 45 from both sides
5a<110-45
5a<65 we divide by 5
a<13
