If the algebraic equation shown is true, write true on the line. If the algebraic equation is not true, cross out the value for the variable and write a new value on the line to make it true. example:
a-1=6,a=8
____________
Since this is not true, cross out the 8 and write a = 7 on the line.

0b = 4
Yes, it is always false. Anything times zero will always equal zero. There is nothing you can multiply by zero to make 4.
