Answer:
a = 1
Step-by-step explanation:
1. distribute the -6 on the left into the parentheses. you should get -36a + 30.
2. on the side right of the =, distribute the -2 to get -16 + 10a.
now it should look like -36a + 30 = -16 + 10a.
3. move the terms over to isolate the a value. subtract 30 to the right side to get -46 (-36a=-46+10a)
4. move the 10a on the right to the left by subtracting it to the other side.
(-46a=-46)
5.divide by -46 to get a=1
Simplify 123/8 then multiply 5/8 and x2 then add those two and subtract 6 sry if it's confusing
3.5y - 12 = 1.5(y - 2)
First, expand to remove parentheses.
Second, add '12' to both sides.
Third, simplify '-3 + 12' to get '9'.
Fourth, subtract '1.5y' from both sides.
Fifth, subtract '3.5y - 1.5y' to get '2y'.
Sixth, divide both sides by '2'.
