What is 26 equals 3b-2-7b?
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
What is b if 7b plus 15 equals -34?
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
Negative parenthesis 3a plus 7b parenthesis minus 8a minus 4b plus 2?
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
No answer this problem and show work 3b-2 equals 7b plus 4?
Add 2 to each side: 3b = 7b + 6 Subtract 7b from each side: -4b = 6 Divide each side by 4: -b = 1.5 Change sign: b = -1.5
What is 26 equals 3b-2-7b?
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
What is 26 equals 3b - 2 -7b?
26 = 3b - 2 - 7b 28 = -4b b = -7
Which expression is equivalent to 7b plus 4b-1b?
It is: 7b+4b-1b = 10b when simplified
What is b if 7b plus 15 equals -34?
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
What is 3a plus 4b plus 6a plus 3b in algebra?
9a + 7b *remember to look and understand the letters!*
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
Negative parenthesis 3a plus 7b parenthesis minus 8a minus 4b plus 2?
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
4b plus 3 equals 15 solving two step equations?
4b+3=15 4b=15-3 b=(15-3)/4 b=3
What is 1a plus 2a plus 3b plus 4b and what is the answer?
1a+3b 2a+4b=3a +7b
No answer this problem and show work 3b-2 equals 7b plus 4?
Add 2 to each side: 3b = 7b + 6 Subtract 7b from each side: -4b = 6 Divide each side by 4: -b = 1.5 Change sign: b = -1.5
A plus 3b plus 5a plus 4b?
6a+7b
What is 4b plus 7b plus 5 equal?
4b plus 7b plus 5 will equal 11b plus 5. When you have two variables that are the same you can add the two numbers with the variables remaining the same.
