2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.
-3b=96+b -4b=96 b=-24
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
3b2 + b - 10 = 0 This quadratic equation can be factored. (3b -5)(b +2) = 0 The equation can be solved when either (3b - 5) = 0, or (b + 2) = 0. If 3b - 5 = 0 then 3b = 5 : b = 5/3 If b + 2 = 0 then b = -2 The roots or solutions to this equation are b = 5/3 and b = -2
If 3b = 39 thenb = 39/3b = 13.
It is an equation and the value of b is 3

its -24.
-3b=96+b -4b=96 b=-24
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
3b2 + b - 10 = 0 This quadratic equation can be factored. (3b -5)(b +2) = 0 The equation can be solved when either (3b - 5) = 0, or (b + 2) = 0. If 3b - 5 = 0 then 3b = 5 : b = 5/3 If b + 2 = 0 then b = -2 The roots or solutions to this equation are b = 5/3 and b = -2
If 3b = 39 thenb = 39/3b = 13.
-3b = 96 + b Subtract b from both sides: -4b = 96 Divide both sides by -4: b = -24

3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.
3b + 6 = 12 3b = 6 b = 2
