If you mean 7b-2 = -51 then the value of b is -7
It is an equation and the value of b is 3
If B equals 8, then the equation is: 20-8=? The answer is 12.
it depends on what b is in the equation. Period = 360 degrees / absolute value of b.
7b = 63 Divide both sides by 7:- b = 9
248
7 will be the answer how.... 5A9 + 9C6 - 7B2 ----------- 823 --------- (ie) 9+6-2=3 and carry one ie 1+A+C-B=12 then only (add carry)+5+9-7=8 then A+C-B=11 give max value to A and C ie a=9 and c=9 then 18-B=11 therefore B=7
For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.
a = 15.
The value of B in the equation B - 5.6 = 3.7 is 9.3.
Let's lay out the known information in equations, where B is the number of boys and G is the number of girls. Then we express the number B in terms of G, which is twice as much less 12, or (2G-12) B + G = 51 , and B = 2G - 12 Now, replace the B in the first equation with its value from the second equation (2G - 12) + G = 51 Remove the brackets 2G - 12 + G = 51 Add 12 to both sides 2G + G = 51 + 12 3G = 63 Divide both sides by 3 G = 21 Now, to check if we're right, Replace G in the first equation B + 21 = 51 B = 30 If that's right then 30 = 2(21) - 12 30 = 42 - 12 And it is, so we know that there are 21 girls and 30 boys in ninth grade.
If you mean: 7+2b = 1 then the value of b is -3
It is an equation and the value of b is 3
7bb - 70b + 112 = 7b2 - 70b + 112 = 7(b2 - 10b + 16) = 7(b - 2)(b - 8)
If B equals 8, then the equation is: 20-8=? The answer is 12.

To find an unknown addend, you can use the equation format of addition. For example, if you have the equation (a + b = c) and need to find (b), rearrange the equation to isolate (b) by subtracting (a) from both sides: (b = c - a). This will give you the value of the unknown addend.
