what is c equal to 4(1.5c + 6) - 2c = -9
4(1.5c + 6) - 2c = -9
6c + 24 - 2c = -9
4c = -33
c = ?
4(1.5c + 6) - 2c = -9
multiply 4 x everything within the parentheses.
6c + 24 -2c = -9
combine terms
4c +24 = -9
move 24 to the other side (changing the sign).
4c = -9 -24
combine terms.
4c = -33
divide both sides by 4.
4c/4 = -33/4
c = ? (It isn't an even number)
-8.25 thanks!
correct.
To solve the equation c = 4(1.5c + 6) - 2c = -9, we need to isolate the variable c on one side of the equation.
Here's how we can do it step by step:
1. Distribute the 4 into the parentheses:
c = 6c + 24 - 2c = -9
Simplifying further, we get:
c = 4.5c + 24 = -9
2. Combine like terms:
In this case, we need to combine the terms with 'c'. Subtract 4.5c from both sides of the equation:
c - 4.5c = -9 - 24
Simplifying further, we get:
-3.5c = -33
3. Divide both sides of the equation by -3.5 to isolate 'c':
c = -33 / -3.5
Simplifying further, we get:
c = 9.4286...
Therefore, the solution to the equation c = 4(1.5c + 6) - 2c = -9 is c ≈ 9.4286.
