Answer:

<h3></h3><h3>The answer is 3/10.</h3>

Step-by-step explanation:

First, convert 3/5 into 10ths.

3/5 = 6/10

Now, we know what 3/5 is equal to, we subtract.

9/10 - 6/10 = x

When we subtract, we get 3/10.

So that means, x =3/10

Hope this helps, have a great day, and stay safe.

Ill give brainlyest to anyone who can help
stepladder [879]

Answer:

Step-by-step explanation:

Substitution  method:

y= -2x + 2

x - 2y = 6

so y = (-2x + 2)

Substitute into y

Hence x - 2y = 6 is:

x + 2x +2 = 6    (+2x because there was - in the equations so -×- = +)

3x + 2=6

Then bring 2 to the other side so

3x = 6-2

3x = 4

x = 3/4 or 0.75

To find y :

y= (-2 × 3/4) + 2

y = -1.5 +2

y = 0.5

That's all I can do for now!
