Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 12 ( add 4x to both sides )
3y = 4x + 12 ( divide the terms by 3 )
y = x + 4 ← in slope- intercept form
with slope m = and y- intercept c = 4
---------------------------------------------------
Given
- 5x + 3y = - 9 ( add 5x to both sides )
3y = 5x - 9 ( divide the terms by 3 )
y = x - 3 ← in slope- intercept form
with slope m = and y- intercept c = - 3
It seems like you have the answer already. but heres how its calculated.
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**
so the missing number is 50
**cross multiply 100 and 80 to get 8000 then divide 160<span> into 8000 to get 50**</span>
