Question 708311
to solve for b, you must get b all by itself on the right side of the equal side.  To do this, do the opposite of what's being done to b, and do that to both sides.  b is being divided by 1.6, so to get b by itself, multiply both sides of your equal sign by 1.6:


{{{-0.4*1.6 = (b/1.6)*1.6}}} =


{{{-0.64 = b}}}


Final Answer:  b = -0.64
