Question

Six times the number of cattle less 87 is 999

can you solve that step by step (solve for thee variable)

Answer 1

You have to translate the statement into a mathematical expression...

Six times the number of cattle, if we let c be the number of cattle is:

6c

Less 87 means to subtract 87 so

6c-87

is 999 means

=999

so all together we have:

6c-87=999 now we need to isolate the variable by itself on one side of the equal sign....

6c-87=999 add 87 to both sides

6c=1086 divide both sides by 6

c=181

So there are 181 cattle.
