This is the eqn of a str line. <span>y+4=12/7(x-1) would be clearer if written as
</span><span>y+4=(12/7)(x-1). y+4 = (12/7)x - 12/7.
Multiply all terms by 7 to remove the fractions: 7(y+4) = 12x - 12.
Complete the multiplication: 7y + 28 = 12x - 12.
Arrange the x and y terms on the left side and the constants on the right:
-12x + 7y = -40. This is standard form. Some people might disagree and say that -12x + 7y + 40 is standard form. They are equivalent.

Step-by-step explanation:
Answer:
x=17.5 or 18,y=12.5,or 13
Step-by-step explanation:
20-15 = 5
5÷2 = 2.5
15+2.5 = 17.5
15-2.5=12.5
