If (-2,y) is a solution to the equation 2x-3y=5, what is the value of y? I'm having trouble with this one
just plug in -2 for x:
2(-2)-3y=5
-4-3y=5
-3y=9
y = -3
x+5,ifx=3
To find the value of y, we can substitute the given x-coordinate (-2) into the equation and then solve for y.
Given equation: 2x - 3y = 5
Substituting x = -2 into the equation gives us:
2(-2) - 3y = 5
-4 - 3y = 5
Next, we want to isolate the term with y. Let's start by adding 4 to both sides of the equation to move the constant term to the right side:
-3y = 5 + 4
-3y = 9
Now, we can solve for y by dividing both sides of the equation by -3:
(-3y) / -3 = 9 / -3
y = -3
Therefore, the value of y is -3.
