- 15x = - 5 (3x + 3)
Remove the parentheses on the right side:
- 15x = -15x - 15
Add 15x to each side:
0 = -15
This is obviously not true. But it would have to be true in order for the equation
given in the question to be true. That tells us that there is no number for 'x'
that can make the original equation a true statement. In other words, there is
no solution.
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
15x minus 8=minus 180 3x+8=24
6x-2=x+135x=15x=3
15x = 60 The variable is x.
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
15x minus 8=minus 180 3x+8=24
Divide each side by -15 and x = - 6/15.
15x = 45 Solve for x by dividing both sides by 15. 15/15 x = 45/15 Simplify. x = 3
6x-2=x+135x=15x=3
If: 15x = 360 then x equals 360/15 = 24
Set up the equation and solve: 15x - 8 - 3x = 16 (next add 8 to each side) 15x - 3x - 16 + 8 (next simplify) 12x = 24 (next divide both side by 12 to solve for x) x = 2
15x = 60 The variable is x.
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3

When X = 4, 15X = 15 * X = 15 * 4 = 60
X = 630/15 = 42
