8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
It’s 20% because 10/10 would be 100% and 1/10 would be 10%
You can only do it like '7.5 plus 9.5 plus 13
<span>5(x - 2) + 2x
= 5x - 10 + 2x
= 7x -10
answer
</span>7x -10
3y - 1 < 3
Isolate the y. Treat the less than or equal like an equal sign.
Do the opposite of PEMDAS. First, add 1 to both sides
3y - 1 (+1) < 3 (+1)
3y < 4
Next, divide 3 from both sides
3y/3 < 4/3
y < 4/3
y < 4/3 is your answer
hope this helps
