Simplify: (3x − 2y) − (4x + 5y).
this is 7th grade math
btw.

=−x−7y

Step-by-step explanation:

First, Distribute the Negative Sign:

=3x −2y+ −1(4x+5y),

=3x+ − 2y + − 1(4x) + −1 (5y),

=3x+ −2y + −4x + −5y

Then, Combine Like Terms:

=3x+−2y+−4x+−5y

=(3x+−4x)+(−2y+−5y)

Finally you get the answer :

= −x + −7y

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
