Which value of x makes the following equation true?
3(x - 4) + 54 = -3x
I think it is -6
Which of the following values for x makes the equation 12 =x/4
Which of the following values for x makes the equation
well, does 3(-10)+54 = 18?
To find the value of x that makes the equation true, we need to solve for x. Here's how you can do it step by step:
1. Start by simplifying both sides of the equation:
3(x - 4) + 54 = -3x
3x - 12 + 54 = -3x
2. Combine like terms:
3x + 42 = -3x
3. Add 3x to both sides to get all the x terms on one side of the equation:
3x + 3x + 42 = -3x + 3x
6x + 42 = 0
4. Subtract 42 from both sides to isolate the x term:
6x + 42 - 42 = 0 - 42
6x = -42
5. Divide both sides by 6 to solve for x:
6x/6 = -42/6
x = -7
So, the value of x that makes the equation true is x = -7, not -6. Make sure to double-check your calculations and follow the steps correctly to avoid errors.
it works (I think)
um... no its 8 huh?
well, first of all, check your answer back in the originl
for example if x = 8
3 (8-4) + 54 = -3(8) ????
12 + 54 = -24 I doubt it
Now let me try
3 x - 12 + 54 = -3 x
6 x + 42 = 0
x = -42/6 = -7
now check that back in the original
