78=3c+12-c+4 solve
78=3c+12-c+4
78 = 2c + 16
78 - 16 = 2c
Take it from there.
2c=65
To solve the equation 78 = 3c + 12 - c + 4, you need to combine like terms and isolate the variable c on one side of the equation. Here's a step-by-step explanation of how to solve it:
1. Start by combining the like terms on the right side of the equation: 78 = 2c + 16.
2. Next, simplify the equation further by subtracting 16 from both sides: 78 - 16 = 2c + 16 - 16.
This gives us: 62 = 2c.
3. Now, divide both sides of the equation by 2 to isolate the variable c: 62/2 = 2c/2.
Simplifying this further, we get: 31 = c.
Therefore, the solution to the equation 78 = 3c + 12 - c + 4 is c = 31.
