Can someone please explain how to do this problem: 7n-5=10n+13
Add 5 to both side
7n=10n+18
Then subtract 10n
-3n=18
Finally divide -3 on both sides
n=-6
subtract 7n to the other side
AND subtract 13 to the other side
and also divide 3 to the other side,so
7n-5=10n+13
-5=10n-7n +13
-5-13=10n-7n
-18=3n
n=-6
Sure! I can help you solve this problem step by step.
To begin, let's collect the variables on one side of the equation and the constants on the other side.
Start by moving the term with n to the left side and the constant term to the right side:
7n - 10n = 13 + 5
Next, simplify both sides of the equation:
-3n = 18
Now we have an equation with only one variable, which is -3n.
To isolate the variable n, we need to get rid of the coefficient (-3) that is multiplying n.
To remove the coefficient, we can divide both sides of the equation by -3:
(-3n)/-3 = 18/-3
This simplifies to:
n = -6
Therefore, the solution to the equation 7n - 5 = 10n + 13 is n = -6.
