First solve the equation for 3x
-3x+3y=12
3x=-57-6y
Now substitute the given value into the equation
-(-57-6y)+3y=12
Then solve for y
Y=-5
Then substitute the given value of y
3x=-57-6✖️(-5)
Now solve for x
X=-9
Ordered pairs
(X,Y)=(-9,-5)
Then you are left with your answer:
(-9,-5)
Hope this helps! :3

Step-by-step explanation:
Answer:
the y-intecept of the line is (0, -6)
Step-by-step explanation:
Given the linear equation in slope-intercept form: y = mx + b
where:
<em>m</em> = slope = 4
<em>b</em> = y-intercept = -6
The y-intercept is the value of <em>y</em> when <em>x</em> = 0.
Plug x = 0 into the equation to solve for the y-intercept:
y = 4x - 6
y = 4(0) - 6
y = 0 - 6
y = -6
Therefore, the y-intecept of the line is (0, -6)
You can solve a system using substitution, elimination, or graphing method.
If you solve using substitution or elimination, the variable will cancel out on both sides and you will be left with a number equal to a number. If "number = number" is a TRUE statement, then the solution is ALL Real Numbers. <em>If it is a FALSE statement, then you will have NO solutions.</em>
If you solve using the graphing method and the lines are exactly the same, then the solution is Infinite solutions (aka ALL Real Numbers). <em>If the lines are parallel, then you will have NO solution.</em>
