Answer:
10.
Divide b into thirds, and then add together 2 of those thirds.
15/3 = 5
5x2 is 10.
Sorry if that doesn't make sense but it's how I do it in my head lol.
Answer:
2y = 3x + 21
y = 1.5x + 10.5
plug in, in the second equation
- 4x + (1.5x + 10.5) = 23
-4x + 1.5x + 10.5 = 23
-2.5x + 10.5 = 23
-2.5x = 12.5
x = 12.5/-2.5 = -5
y = 1.5 (-5) + 10.5 = 3
x = -5
y = 3
Answer:
it would be x=17 1/2
Step-by-step explanation:
i am going to go a little more into detail.
you would first have to divide each side to isolate the variable
x=5/2/7
simplifying steps:
you would have to change the 5 into 5/1
5/1÷2/7
now you have to keep the first number, change the sign, and then flip the last number, AKA KCF
5/1*7/2
35/2
and you can simplify this into a mixed number
17 1/2
hope this helps! have a nice day :)
