What is the answer to this problem 2n-5 equals 7?
in algebra, if what you do to one side of the equation you do to the other side you do not change things and you can solve for the unknown 2n-5 = 7 add 5 to BOTH sides 2n-5 + 5 = 7 + 5 2n = 12 Divide BOTH sides by 2 n = 6
What does n equal if 42 equals 2n plus 7?
42 = 2n + 7Subtract 7 from each side of the equation:35 = 2nDivide each side by 2:17.5 = n
2n plus 19 equals -7?
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
What is the answer for 2n -7 for n equals 8?
If 'n' is 8, then (2n - 7) is 9 .
What is the answer to 2n-7 equals 5n-10?
2n - 7 = 5n - 10subtract 2n from each side- 7 = 3n - 10add 10 to each side3 = 3ndivide both sides integers by 31 = n=======check in original equation2(1) - 7 = 5(1) - 102 - 7 = 5 - 10- 5 = - 5========checks

What is 2n - 7 equals -1?
2n - 7 = - 1 add 7 to each side 2n - 7 + 7 = - 1 + 7 2n = 6 divide each sides integer by 2 (2/2)n = 6/2 n = 3 ---------------check in original equation 2(3) - 7 = - 1 6 - 7 = - 1 - 1 = - 1 ----------------checks and equation is satisfied
What is the value of n if 2n plus 7 equals 19?
2n plus 7 equals 19 2n equals 12 n equals 6
What is 3n plus 5 equals 2n plus 7?
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:

How do you solve 4n-7 equals 5-2n?
Here is one way. Start with: 4n - 7 = 5 - 2n add 2n to both sides to give: 6n - 7 = 5 add 7 to both sides to give: 6n = 12 divide both sides by 6 to give: n = 2
5 plus 7 equals -12 factor equation?
There is no equation. An equation is true, whereas the statement ( 5 + 7 = -12 ) is false.
Write the equation that describe the sequence 1 3 5 7?
tn = 2n - 1 where n = 1,2,3,...
