Graphing equation question? how would solve this linear equation?

hello

I don't understand how to solve equations like these of graphing when it has A FRACTION so if someone could show me how to solve this problem and how DO YOU multiply a fraction in a graphing linear equation I WOULD APPRECIATE IT!!

Consider the equation 2x+3y=12.Find the value of x when (x,11/3) that makes the given ordered pair a solution to the equation??

Solve 2x + 3 (11/3) = 12

please help and show me how to multiply fractions in these type of problems thank you

2x + 3 (11/3) = 12
first you multiply the 3 into 11/3 and you'll now have
2x + 11 = 12
next subtract 11 from both sides
2x = 1
finally divide by 2 in both sides
x = 1/2 or .5

Simplify by solving 3(11/3) = 11 to get
2x + 11 = 12

Now you can solve for x by first subtracting 11 from both sides of the = to get
2x = 1

Finally divide both sides by 2 to get
x = 1/2

2x + 3(11/3) = 12

3/1 * 11/3 = 33/3 When multiplying, just multiply across, numerator to numerator and denominator to denominator.

(I know I put a 1 under the 3, all whole numbers have a 1 under them) (example : 3/1 = 3) or ( lets say 5 in fraction form is 5/1 ) (Another fraction example 2/5 * 3/4 mult across and you get 2 * 3 = 6 and 5 * 4 = 20 answer 6/20 then, simplify and get 3/10)

Now simplify 33/3 = 11

2x + 11 = 12 Now subtract 11 from both sides. and you get 2x = 1

2x = 1 Now divide 2 on both sides and you get x = 1/2

ordered pair is (1/2 , 11/3)
