Y=4x-18 is the parallel equation
Y=mx+b Substitute
2=4(5)+b Multiply by 5
2=20+b Substract 20 in both sides
-18=b
x-(x/3)=2
turn x into a fraction x/1
to get x/1 -x/3 = 2
multiply x/1 x 3/3 to get both fractions with same denominator
3x/3 - x/3
(3x-x)/3
3x-x = 2x
so now you have (2x)/3 =2
multiply both sides by 3 to get 2x = 6
divide bothe sides by 2 to get x = 3, which is the answer
simplify -7.39 -(-4.8)- 5.32 = -7.91
