My Daughter having problem with this how to explain

2/3 (y) - 1/2(x) =? When x= -2 and y= 3. She just started math grade 10 but not understanding teacher. Whats is easy way to explain this problem. Thank to all

2/3(y) - 1/2(x)
2/3(3) - 1/2(-2) = 2*3/3 + 1*2/2 = 2 + 1 = 3

The first term is two thirds of three is two
The second term is half of two which is one.
As to the minus by minus being plus, I regret to say I can suggest little that will convince her other than that she must remember this.

If the problem looks like 2/3y - 1/2x I think I know what you are talking about. When the variable (letter) is attached to a number (in this case a fraction) you would multiply those numbers. So it would be 2/3(3) which equals 2. Then you would take 1/2(-2) which is -1. So rewrite the equation 2 - -1 and because there are double negatives you change the subtraction to addition and change the negative one to positive one. 2 + 1 = 3

A bracket means that you multiply the number before the bracket by
what is inside it.
So if y is 3 it means she should multiply 2/3 by 3 = 6/3

And if x is -2 she multiplies -1/2 by -2
Two minus multiplied by each other always become PLUS.
So: - 1/2 times -2 is 1.

Finished: Now it sais: 6/3 + 1 = 1 6/3 which is the same as 3.

I DO hope I did not make any mistakes here...

2/3 (y) - 1/2(x) =? when x = -2 and y = 3

All you have to do is sub in your values of x and y into the equation

2/3(3) - 1/2(-2)

= 2 - (-1) = 3

so your answer is 3

2y/3 = 2 when y = 3
-x/2 = +1 when x = - 2
2 + 1 = 3 (answer)

"my daughter" um yeah right
