Ответ:
x = (- mf – ac) / (ad – mk).
Объяснение:
1) ax = b;
х = b / a.
2) ax + b = c;
ax = c – b;
х = (c – b) / a;
3) a * (dx - c) = ax + b;
adx – ac = ax + b;
adx – ax = b + ac;
x * (ad – a) = b + ac;
x = (b + ac) / (ad – a).
4) ax - b = c;
ax = c + b;
x = (c + b) / a.
5) a * (dx + c) = m * (kx - f);
adx + ac = mkx – mf;
adx – mkx = - mf – ac;
x * (ad – mk) = - mf – ac;
x = (- mf – ac) / (ad – mk).
