Isolate the x. Note the equal sign. What you do to one side you do to the other.
Subtract 2y from both sides
2x + 2y (-2y) = 10 (-2y)
2x = 10 - 2y
Isolate the x, divide 2 from both sides and from all terms.
(2x)/2 = (10 - 2y)/2
x = 5 - y
Place the variable in the front
x = -y + 5
x = -y + 5 is your answer
hope this helps
It can be any number so here is my awnser 437
First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.
The pairs of f(x) =-3x+5 can be found by putting value of x and getting f(x).
x=0, f(x)=5
X=-1, f(x) =3+5=8
x=1, f(x)= -3+5=2
So few ordered pairs arw (0,5) ,(1,2),(-1,8) etc.
