Which describes a correct method for solving this equation 15+3x=18
A divide both sides of the equation by three and then add 15 to both sides
B subtract 15 from both sides of the equation, and then divide both sides by three
C divide both sides of the equation by three and then subtract 30 from both sides
D add 15 to both sides of the equation and then divide both sides by three
The correct method for solving the equation 15+3x=18 is:
A) Divide both sides of the equation by three and then add 15 to both sides
Explanation: The equation can be solved by isolating the variable x on one side of the equation. Start by subtracting 15 from both sides:
15+3x - 15 = 18 - 15
3x = 3
Next, divide both sides of the equation by 3:
(3x)/3 = 3/3
x = 1
