Answer:
Step-by-step explanation:3(x - 2) + 5x = 9x - 24
Given
3x - 6 + 5x = 9x - 24
Distributive Property
3x + 5x - 6 = 9x - 24
Commutative Property of Addition
8x - 6 = 9x - 24
Combine Like Terms
8x - 8x - 6 = 9x - 8x - 24
Subtraction Property of Equality
0 - 6 = x - 24
Additive Inverse Property (left)
Combine Like Terms (right)
-6 = x - 24
Additive Identity Property
-6 + 24 = x - 24 + 24
Addition Property of Equality
18 = x + 0
Addition (left)
Additive Inverse Property (right)
18 = x
Additive Identity Property
Answer:66
Step-by-step explanation:
6+60=66
Y = 3
This is because according to the all the numbers we have, all they did was divide the numbers from the bigger triangle by 2. So, 10 divided by 2 is equal to 5. That is where the 5 came from. 7 divided by 2 is equal to 3.5. That is where the 3.5 came from. 6 divided by 2 is equal 3. That is why y is equal to 3.
Hope this helps, have a great day, stay safe and positive.
