4) -1/2(y-x)
Multiply -1/2 to y and x
-1/2y+ 1/2x
5) a(8+2b-6)
Multiply a to the equation in parentheses
8a+2ab-6a
Add like terms which are 8a and -6a
2ab+2a
6) -2.5(-3+4n+8)
Multiply-2.5 to the equation in the parentheses
7.5-10n-20
Add like terms which are 7.5 and -20
-10n-12.5
Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:
Don't multiply or divide by a variable (unless you know it is always positive or always negative)
