A fruit stand has to decide what to charge for their produce. They need $5.30 for 1 apple and 1 orange. They also need $7.30 for 1 apple and 2 oranges. We put this information into a system of linear equations.
Can we find a unique price for an apple and an orange?
Choose 1
Yes; they should charge $3.30 for an apple and $2.00 for an orange.
Yes; they should charge $2.00 for an apple and $3.50 for an orange.
No; the system has many solutions.
No; the system has no solution.

so, converting firstly the mixed fractions to improper fractions and then "adding".

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
