solve 4x+3=47
To solve the equation 4x + 3 = 47, you need to isolate the variable x on one side of the equation. Here's how you can do it:
1. Start by subtracting 3 from both sides of the equation:
4x + 3 - 3 = 47 - 3
This simplifies to:
4x = 44
2. Next, divide both sides of the equation by 4 to solve for x:
(4x) / 4 = 44 / 4
This simplifies to:
x = 11
So the solution to the equation 4x + 3 = 47 is x = 11.
solve 1/3x=12
To solve the equation (1/3)x = 12, you need to isolate the variable x on one side of the equation. Here's how you can do it:
1. Start by multiplying both sides of the equation by 3 to eliminate the fraction:
3 * (1/3)x = 3 * 12
This simplifies to:
x = 36
So the solution to the equation (1/3)x = 12 is x = 36.
solve 3x+3=21
To solve the equation 3x + 3 = 21, you need to isolate the variable x on one side of the equation. Here's how you can do it:
1. Start by subtracting 3 from both sides of the equation:
3x + 3 - 3 = 21 - 3
This simplifies to:
3x = 18
2. Next, divide both sides of the equation by 3 to solve for x:
(3x) / 3 = 18 / 3
This simplifies to:
x = 6
So the solution to the equation 3x + 3 = 21 is x = 6.
solve 3/2x-4=16
To solve the equation (3/2)x - 4 = 16, you need to isolate the variable x on one side of the equation. Here's how you can do it:
1. Start by adding 4 to both sides of the equation:
(3/2)x - 4 + 4 = 16 + 4
This simplifies to:
(3/2)x = 20
2. Next, multiply both sides of the equation by 2/3 to solve for x:
(2/3)(3/2)x = 20(2/3)
This simplifies to:
x = 40/3
So the solution to the equation (3/2)x - 4 = 16 is x = 40/3 or x = 13.33 (rounded to two decimal places).
