3x = 5x - 10
Subtract both sides by 5x
3x - 5x = 5x - 10 - 5x
Simplify
- 2x = - 10
Divided both sides by -2 to isolate x
- 2x / - 2 = - 10 / - 2
Simplify
x = 5
Plug x into the original equation.
3(5) = 5(5) - 10 = ?
Simplify
15 = 25 - 10 = ?
Simplify
15 = 15 = ?
Therefore 3x = 5x - 10 = 15
3x+12 = 18 3x = 18-12 3x = 6 x = 2
y = 3x = 12y = 12
no
3x-3x equal = 0
y equals 3x has the greater slope.
If x-3x=18 then x equals -9
3x=81 3x/3=81/3x=27
3x + 2 = 3x + 6 This is not possible.
3x-5=3x+5 There is no solution.
y = 15 (by transitivity)
(2, -1)
Their graphs are.
