B=+%284%2F7%29%28A-11%29 Start with the given equation.


%287%2F4%29B=+cross%28%287%2F4%29%284%2F7%29%29%28A-11%29 Multiply both sides by the reciprocal of 4%2F7. This gets rid of the 4%2F7 on the right side.


%287%2F4%29B%2B11=A%2Bcross%28-11%2B11%29 Add 11 to both sides.


%287%2F4%29B%2B11=A Simplify.


So the answer is A=%287%2F4%29B%2B11
