Answer:
I think the error is that the variable x came before the whole number 2.
Rob has R quarters, and David has R + 24 or 24 more than rob, so together they have 2R+24
Answer:
6y + 5x - 3
Step-by-step explanation:
Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.
Given the expression;
2y – 3 + 7x + 4y – 2x
Collecting like terms, we have;
Expression = 2y + 4y + 7x - 2x - 3
Expression = 6y + 5x - 3
