if twice a number is decreased by 5 and that result is multiplied by 4, the result is 36
1. Replace the words "a number" by x
if twice x is decreased by 5 and that result is multiplied by 4, the result is 36
2. Replace the words "twice x" by 2x
if 2x is decreased by 5 and that result is multiplied by 4, the result is 36
3. Replace the words "is decreased by" by a minus sign:
if 2x-5 and that result is multiplied by 4, the result is 36
4. Delete the words "and that result" (for we already have that result 2x-5).
Put parentheses around (2x-5)
if (2x-5) is multiplied by 4, the result is 36
5. Delete "If" and "is multiplied by", and move the 4 in front of the (2x-5)
4(2x-5), the result is 36
6. Replace the words "the result is" with an equal sign " = ". Delete the comma.
4(2x-5) = 36
7. It's translated. You finish it.
