Assuming the equation is 3x=15, you just need to divide each side of the equation by three. On the left, x times three divided by three is one times x, or just x. On the right side, fifteen divided by three is five. So you are left with x=5.

What 3x 45 and how do you solve for x?
Do you mean 3x = 45 then if so divided both sides by 3 to find the value of x which is 15
How do you solve the equation -3x minus 5 equals -20?
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
How do you solve 8-3x equals 128?
8-3x = 128 -3x = 128-8 -3x = 120 x = -40
3x equals 96-75 solve for x?
3x = (96-75) 3x = 21So X = 7
15 plus 3x 42 then x?
If 15 + 3x = 42, then x = 9
How do you solve for -3x-3y equals -15?
solve -3x-3y=-15
How do you solve 4x plus 7-3x equals 15?
4x+7-3x = 15 4x-3x = 15-7 x = 8
Solve negative 3x - 2 17?
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
3x plus 5 equals 20 solve equation?
3x plus 5 equals 20: 3x + 5 = 20 3x + 5 - 5 = 20 - 5 3x = 15 3x/3 = 15/3 x = 5
How do you solve negative 3x plus 5 equals 20?
-3x + 5 = 20 -3x = 15 x = -5
How to Solve the equation for y 3x-5y equals 15?
3x-5y=15 The equation-5y=15-3x Subtract 3x from both sidesy=-3+.6x Divide both sides by -5
Darius is asked to solve the equqtion x plus 5 equals 4x over 3?
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15
What is 25 divided by 5x divided by 15 divided by 3x simplified and what are the steps to solve it?
Since there are no brackets or parentheses, the divisions must be evaluated from left to write so that the expression is ((25/5x)/15)/3x = ((5/x)/15)/3x = (5/15x)/3x = (1/3x)/3x = 1/(9x2)
What is the solution of 8 minus 3x equals 23?
8-3x=238-8-3x=23-8 subtract 8 from both sides-3x=15-3x/-3 = 15/-3 divide both sides by -3 to solve for xx = -5
How do you solve 3x equals 15?
3x = 15 >> 3x = multiplication, and the opposite of multiplication is division. So you take 3x, draw a line under it to show division, then write 3. After that, cross out the 3x/3. With algebra what you do to one side, you do to the other, so then you take 3 and divide it by 15. >>the answer>> X=5
Could you please solve for X 3x plus 5 equals 4x - 10?
3x+5 = 4x-10 In algebra, what you do to one side you do the other Now you add 10 to both sides 3x+5 + 10 = 4x-10+10 3x +15 = 4x now subtract 3x from both sides 3x-3x +15 = 4x-3x 15 = x
-3 plus 3x plus 6x equals 15?
To solve the equation -3 + 3x + 6x = 15, combine like terms: 9x - 3 = 15. Then, add 3 to both sides: 9x = 18. Finally, divide both sides by 9 to solve for x: x = 2.
