Answer:
x= -1, y= 6
Step-by-step explanation:
9x + 7y =33---a
-6x = y---b
Put b into a,
9x + 7(-6x) = 33
9x - 42x = 33
-33x = 33
x = -1----c
put c into b,
-6(-1) = y
y=6
Answer:
The answer is (-1, -6)
Step-by-step explanation:
To get y by itself, you switch sides of the Y and the -6x
9x+7y=33
y= -6x
You then put the -6x where the y is
9x+ 7(-6x) = 33
9x -42x =33 9 -42 = -33
-33x = 33
It's now a one-step equation
x= -1
Now you put the x value (-1) where the x is in y= 6x
y= 6 (-1) y=-6
