First you have to isolate the y value
to start, subtract 2x on both sides
3y=-2x+9
next, divide by 3
y= -2/3x+3
Answer:
12
Step-by-step explanation:
20² - 16² = x²
400 - 256 = x
400 - 256 = 144
√144 = 12
Answer:
(2,-8)
Step-by-step explanation:
y have
y=3x-14
y=x-10
we can substitute y in the first equation with x-10
x-10=3x-14
solve for x
4=2x
x=2
Now that we know what x equals we can solve for y
3(2)-14
6-14
-8=y
(2,-8)
