Question

The point (2,y) is a solution to the equation -2x+3y-4=0. What is the value of y?
F. -3
G. 0
H. 8/3
J. 4

Answer 1

(2,y) means x = 2 and y is unknown (we just leave it as y for now)

Answer 2

Go to the equation -2x+3y-4=0 and plug in x = 2

-2x+3y-4=0

-2(2)+3y-4=0 ... replace every copy of x with 2

-4+3y-4=0

3y - 8 = 0

...
...
...

y = ??

Answer 3

Is my answer j?

Answer 4

what do you get when you solve for y in 3y - 8 = 0

ignore the answer choices for now

Answer 5

Y=-2.6

Answer 6

write that as a fraction and the answer should be positive (not negative)

Answer 7

2/6

Answer 8

that's not correct

Answer 9

I don't have a calculator to put in a fraction

Answer 10

3y - 8 = 0

3y - 8+8 = 0+8 ... Add 8 to both sides.

3y = 8

what's the next step?
