Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
Answer:
i don't know..........,......
The answer simplified is:
a= —2x^2+7x+22
If a=6 and the equation is 4+2a. This is how you wold solve it: 4+2(6)= 4+12= 16. So your answer is B. 16
Hope this helps
