Solve for u. -24 = u ÷ 6 u = ____

kati45 [8]

The value of u is -144

Solution:

Given that,

$-24 = u \div 6$

We have to solve for "u"

From given,

$-24 = u \div 6$

Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign

Thus we get,

$-24 = u \times \frac{1}{6}\\\\\frac{u}{6} = -24$

Isolate for u

$u = -24 \times 6\\\\On\ multiplying\ both\ we\ get\\\\u = -144$

Thus the value of u is -144
