17 = 13 - 3r
Subtract 13 from bith sides: 4 = -3r
Divide both sides by -3 : -4/3 = r or r = -1.3...

6A - 58 = 44 Add 58 to both sides: 6A = 102 Divide both sides by 6: A = 17

y = 12x + 5x - 7 Since '12x' and '5x' both have the same variable, you are able to combine them. To do this you just need to add 12 + 5 to get 17. After doing this you can rewrite the equation as y = 17x - 7. You can then solve this equation for different values by plugging in a number for 'x' or 'y' or graphing the equation.
(4 ± i2) where i2 = -1
The answer depends on what it is that you want to do. You cannot solve a single linear equation in two variables.
Add 8
t - 17 = 48 The first step is to move the -17 to the right side of the equation and end up with: t = 48 + 17. (When you switch sides, the sign changes) To solve the equation: t = 65
If 6A - 58 = 44 then 6A = 102 making A = 17.

3x+5=17
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
6A - 58 = 44 Add 58 to both sides: 6A = 102 Divide both sides by 6: A = 17

p - 33 = 17 Add '33' to both sides Hence p - 33 + 33 = 17 + 33 p = 50
