A = h/2*(a + b)

So 2A/h = a + b

and therefore, a = 2A/h - b

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

If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2

Using the quadratic equation formula: x = 8.42 or x = -1.42

solve -3x-3y=-15

You do not need to transpose anything to get the formula for the area of a trapezium! (I need the transpose the formula so a is the subject thank you)

You can't solve a formula with no equals sign

Please clarify what you want to "solve". There are several operations you can do with matrices, such as add them, multiply them, transpose them, etc.

Solve using the quadratic formula

C= pi * D This is the formula for circumference.

Quadratic equation formula

te formulae is a half[a plus b]height

Not sure about the original formula, but one that works is b = a/(2c + 1)

c= a-2b

If you can't factor it easily, use the quadratic formula.

a-2b=c
