Answer:
20
Step-by-step explanation:
The answer would be 20 due to the fact that it would have to be 50 divided by 2.5 to get the answer of how many steps and 50 divided by 2.5 would equal 20
A= 3,2
B= -1,-1
C= 3,4
D= 1,4
Let's write the equation with formula:-
Where,
- x1 is -1 and y1 is 4 and m is 3
<em>Thus, The correct choice is option C!!~</em>
(2x-3y=-4)-2(x+3y=7)
2x-3y-2x-6y=-4-14
-9y=-18
y=2, making x+3y=7 become:
x+6=7
x=1
So the solution to the system of equations is the point (1,2)
