Step-by-step explanation:
marlena steps should look like this:
2x + 5 = -10 - x
(minus 5 from both sides)
2x = -15 - x
(add x to both sides)
3x = -15
(divide by 3)
x = -5
Answer:
3,12,21
Step-by-step explanation:
You add 9 to the number each time so the next 3 terms will be....
-6+9 =3
3+9=12
12+9=21
What does the question say
Answer: 26
Step-by-step explanation:
to solve this series, we should find a pattern first.
if we look at the differences of each number, we can see that
4-1=3
8-4=4
13-8=5
19-13=6
to find the next number in the series, it would be 7 more than 19, since are counting upwards from 3.
I’m sorry if I’m wrong but the equation be 3x+6=2x and if you solve that, x=6.
Explanation: 3x+6=2x
-3x. -3x
6=x
