Question 909044
b÷17+4=-4 
Assuming there are no parentheses, follow the <a href=http://www.algebra.com/algebra/homework/expressions/Using-the-Order-of-Operations.lesson>Order of Operations</a>.

Do the division first.
{{{b/17}}} +4 = -4
Subtract 4 from each side
{{{b/17}}} = -8
Now multiply each side by 17 to get rid of the pesky fraction
b = -136

<b>IF</b> there had been parentheses around (17+4), you would do that first.
b / 21 = -4
Multiply each side by 21
b = -84
