Two lines in a plane can intersect,overlap or be parallel.When two lines intersect they have a common point which lies on both line.This is called solution of the two simultaneous equation which when graphed represent straight lines. Adding the two equations uses Elimination method to solve for x and y. The x and y value obtained is the common point lying on both the lines.
2x - 3y = 1
+ 2x + 3y = 2
4x =3 Or x=3/4
Substituting x value in any of the two-equation we can find the corresponding y value .
2x-3y=1
2(3/4) - 3y =1
Solving for y
y= 1/6
The point of intersection of the two lines is ( 3/4, 1/6)

The expression for the sequence of operations described below is d/3 + 5
<h3>Expressions and equations:</h3>
- Let the unknown value be "d"
- d divided by 3 is expressed as d/3
Adding 5 to d/3 to get the expression below;
g(d) = d/3 + 5
Hence the expression for the sequence of operations described below is d/3 + 5

Answer:
ok so first we know that 1/3 of a hour is 20 minutes since
60*1/3=20
so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15
20*15=300
300 minutes or 5 hours
Hope This Helps!!!
Y=3x+4.5 is NOT the equation the correct answer is what the person under me typed
Point slope form: y-y1 = m(x-x1)
Find slope: (y2-y1)/(x2-x1)
(1-5)/(9+3) = -4/12 = -1/3
Point slope equation: y+5 = -1/3(x+3)
Slope intercept: y = -1/3x - 1 + 5
Final slope int equation: y = -1/3x + 4
