If 4 is subtracted from twice a number, the result is 10 less than the number. find the number

The difference of 2 numbers is 21 and the quotient of the equation is 4 then what are the two numbers?

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright

Evaluate the expression for the given value of the variable 2×(c2-5) for c=4
