There is no "formula" to solve this kind of equation; you simply have to put get the desired variable on the left side, and everything else to the right side.

a = 3b - 2c

Switch around:

3b - 2c = a

To get rid of the "2c", add "2c" to each side:

3b = a + 2c

To get rid of the 3, divide both sides by 3:

b = (a + 2c) / 3.

How do you solve y equals mx plus b solve for b?

b = y - mx.


How do you Solve the formula y equals mx plus b for M?

How do you transpose A equals half h times a plus b to solve for a formula is for a trapezium?

A = h/2*(a + b) So 2A/h = a + b and therefore, a = 2A/h - b


A plus b equals 8 and a minus b equals 9?

Solve one of the formulas for A, then substitute that into the other formula to solve for B, then substitute the solution for B into one of the formulas to solve for A. Here is how: Givens: A+B=8 A-B=9 So: If A+B=8 then A=8-B Next, substitute this into the other formula... A-B=9 (8-B)-B=9 (-B) - B = 1 (-2B) = 1 B= (- 1/2) Next, substitute the solution for B into one of the formulas to solve for A.... A+B=8 A+ (-1/2) = 8 A = 8 and 1/2 So... B= (- 1/2) A = 8 and 1/2
