Question

if the expression 4x-3 is equal to 11 for some value of x, then what is the expressiom 4x-1 equal for the same value of x

Answer 1

Answer: 13

Explanation:

Add 3 to each side. That original 3 is cancelled out so you're left with 4x=11. Divide each side by 4 and that leaves you with x = 3.5

Now all you have to do is multiply 4 by 3.5 which is 14. You now have to subtract 1 and your answer is 13.
