1.
5 x - 1/3 = 4
2.
(4/5) x - 3 = 7
3.
r s = u - t
s = (u-t)/r
4.
n = q - m/p
There are 4 problems that I don't understand how to solve so, please help me. A numerical explanation with words explanation would be nice. Thank you tutors.
Rewrite each equation so it is in the form ax + b = c or x + d/e = f, where x is a variable. Then solve the equation.
1. 6 + 5x - 1/3 = 10
2. 7 + 3 - 4x/5 = 0
In each equation, one of the letters represents a variable and the other letters represent constants. Solve for the indicated variable and describe what operations you performed to solve for the variable.
3. Solve rs + t = u for the variable s.
4. Solve n + m/p = q for the variable n.

Thank you tutor Damon. I still don't understand, for the equation you gave me for #2, I got x = 12.5 and when I check it, 3 - 50 = -47/5 = -9.4 + 7 = -2.4 and not 0. For #3 and 4, I still don't understand how to solve it.

(4/5) x = 10
4 x = 50
x = 12.5
------------
check
10 - (4/5)12.5
10 - 50/5
10 - 10
0 yes
