thank you (=In the equation 10 = 3b = -11, what number can be used in place of b to make the equation true?
10 = 3b = -11
No value of b will make 10 = -11
Is there some typo?
Maybe:
10 - 3b = -11
Add -10 to both sides:
-3b = - 21
Divide both sides by -3:
b = 7In the equation 10 = 3b = -11, what number can be used in place of b to make the equation true?
Unless I'm mistaken, omitting the 3b altogether leaves: 10 = -11
That's not going to work no matter what you do to b
Did you omit something?
If you meant to type: 10 - 3b = -11
3b = 10 + 11
3b = 21
b = 21/3
b = 7
Otherwise, no value of b can make 10 = 3b = -11 true.
10-3b= -11
-3b= -21
b=7
None
