8 = r - 5
Adding 5 to both sides of the equation, we have
8+5 = r-5+5,
or simply, 13 = r.
Hence, r=13 is the solution.

You cannot solve one equation in two unknowns.
This is not an equation. (8/8) times (8 and 8/8) = 9

x=10 y=4
15x minus 8=minus 180 3x+8=24
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
This is an inequality equation in the form of: ii < xxii/viii which is the same as 2 < 22/8
