Q. Simplify the expression. Write your answers using integers or improper fractions.−(−2y+8)+21yAnswer:
Distribute Negative Sign: First, we need to distribute the negative sign across the terms inside the parentheses. −(−2y) becomes +2y, and −8 becomes −8.
Combine Like Terms: Now we combine the like terms. We have 2y from the first expression and (1/2)y from the second expression.2y+(1/2)y=(4/2)y+(1/2)y=(5/2)y
Subtract Constant: Finally, we subtract 8 from the (25)y term, since there are no like terms to combine with −8. (25)y−8 is the simplified expression.
