Answer:
x = 7
Step-by-step explanation:
Opposite number or additive inverse of any number (n) is a number which, if added to n, results in 0, the identity element of addition. You can say that the opposite number of a number, is the negative version of the positive number. This is what the opposite of 4 is or the opposite of -4
your formula will ALWAYS be Y=MX+B
3x + Y = 6
subtract 3x from each side
Y = -3x + 6
you’ll use rise over run, 1/3 will be your ratio.
