x+y=0
Step-by-step explanation:
x= 1.75
y= -1.75
Answer:
x=-4.5 or x=-2/9(fraction)
Step-by-step explanation:
3x^2-6x-2=0 simplify so add 3 minus 6 then do ^2
-9x-2=0 Add 2 on both sides
-9x=2 divide by -9 on both sides
x=-4.5 or x=-2/9
Plug in three.
y= 2(3) +3
y= 6+3
y=9
I hope this helps!

Answer:
Q1. 20x = 200. The value of x is 10
Q2. 7 - 3x = 1. The value of x is 2.
Step-by-step explanation:
In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :
Let number = x,
Same for the next question. Given that a number multiplied by 3 :
Let number = x,
Then subtracted by 7 equals to 1 :
