Answer:
x = 6, y = 3
Step-by-step explanation:
Let Sally's age be x and Tomas's age be y.
Sum of Sally's age plus twice Tomas's age: x + 2y = 12
Difference of Sally's age and Tomas's age: x - y = 3
Multiply the second equation by two and add it to the first equation to get
3x = 18, which means x = 6.
Plug 6 in for x in the second equation to get 6 - y = 3, which means y = 3.

Answer:
x > -3_2/3
Step-by-step explanation:
(3x+6)-2 < 10
Distribute
-6x-12 < 10
+12 +12
-6x < 22
-6x/-6 < 22/-6
When you divide by a negative number you flip the inequality
x > 22/-6
Simplify
x > -3_2/3
