2b-8=-b+7
3b-8=7 Add 'b' to both sides, eliminating the variable on the right side
3b=15 Add 8 to both sides to isolate the number on one side
b=5 divide each side to eliminate the coefficient on b.
The answer is b=5.
The values of a and b are 7 and 18 or 18 and 7
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
A^2 + b = 7 A + B^2 =11 -------------- A=2 and B=34(2^2) + 3 = 7 2 + 9(3^2) = 11
To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.
the answer is a

If: 7+3b = 61 Then: b = 18
b=7
That depends what the values of k and b are.
x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
We are given that a + b = -7 and b = 10 Therefore a +10 = =7 Subtract 10 from each side So a + 10 - 10 = -7 + 10 Which simplifiesn to a = 10 - 7 So a = 3
