Answer:
k=11
Step-by-step explanation:
3(k - 6) = 15
Divide each side by 3
3/3(k - 6) = 15/3
k - 6 = 5
Add 6 to each side
k-6+6 = 5+6
k = 11
Answer:
1. 21/25
2. 72
3. -4
4. Typo?
2I+2w= 33
21+2w=34
5. Dont understand this question withought context
Step-by-step explanation:
1. 84/4 and 100/4 is 21/25
2. 3(6)(-4) miltiplication
3. worry about parenthesis first, a positive plus a negatative goes to minus so 6-4 then multiply 2 times -2 and get -4
4.
2I+2w is 2(10)+2(6.5)
21+2w is 21+2(6.5)

Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
