To solve for b, you must form an equation (-5b -12 -2 = 0). Next you must separate the known numbers from the unknown by adding the sum of the knowns to both sides of the equation (-5b = 14). Then divide both sides of the equation by -5 to find the value of b (b = -2.8).

-5b - 12 -2?
Not sure how the problem is set up as I see a space between the minus sign and the 12 but not between the minus and the 2. But, using the numbers as written: To solve for b, you must form an equation (-5b -12 -2 = 0). Next you must separate the known numbers from the unknown by adding the sum of the knowns to both sides of the equation (-5b = 14). Then divide both sides of the equation by -5 to find the value of b (b = -2.8). No no no no no. It is -5b-14 because the -5b has no relation to the others so it stays as it is and then -12-2=-14 thus getting -5b-12-2=-5b-14. Cool.
What is the aswer -b plus 5b-2b?
-b+5b-2b=2b
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
How do you solve 5b squared equals 8b?
5b2 = 8b therefore 5b =8 therefore b = 1.6
Does 7b minus 2 equal 5b?
No. 7b - 2b = 5b
-5b - 12 -2?

One number is 5 times a second number The sum of the numbers is 72. What are the numbers?
12 and 60 ============ a + b = 72 a = 5b replacing a by 5b in the first equation 5b + b = 72 6b = 72 b = 12 72 - 12 = 60
What is the value of b if the sum of 5b and 21b is equal to 12?
5b + 21b = 1226b = 1226 26b = 12/26
What is 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
What is b when 5b equals 30?
If: 5b = 30 Then: b = 6
How do you solve similtaneously -5a plus b equals 2 and -a -5b equals 0?
-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13
What is the aswer -b plus 5b-2b?
-b+5b-2b=2b
What are 2 equivalent expressions for 5b plus 5b?
5b + 5b = 2 x 5b
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
2(a plus b) plus 3(a plus b) plus 5a?
10a + 5b
10a-5b equals 25 what is b?
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
How do you solve 2 bracket X minus B bracket equals 5B plus 3 making X the subject?
2 [x - B] = 5B + 3Perform the indicated multiplication on the left side:2x - 2B = 5B + 3Add 2B to each side of the equation:2x = 7B + 3Divide each side by 2 :x = 7/2 B + 3/2
