Answer:
I do not know what math curriculum this is I'm sorry
I want to say the answer is a or b mostly a though
There is no commutative property for subtraction and division because order does matter. 6 - 5 will not give you the same answer as 5 - 6.
To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.
y = x + 2
3y = 4x - 2
3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10
solution:
x = 8
y = 10
hope this helps!! :)
<span>A is the correct answer. To find 10% of 50, divide it by 10. This gives you 5. If 5 is 10%, then 20 is 40%, because 20 is 4 x 5 and 40 is 4 x 10. </span>
