The simplified solution to this equation is 5x - 115.
Hmmm... try subtracting or multiplying the other numbers??
Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (3, 11) and (x₂, y₂ ) = (6, 17) ← ordered pairs from the table
m = = = 2 → A

Answer:
Option 3:
elimination using multiplication (3,-1)
Step-by-step explanation:
The system of equations to be solved are
-5x+3y=-18.......eqn (1)
2x+2y=4. .......eqn (2)
We first multiply eqn(1) by 2 and eqn(2) by 5 to get eqn(3) and eqn(4) respectively.
This implies
-10x+6y=-36.......eqn (3)
10x+10y= 20.......eqn (4)
we then add eqn(3) and eqn(4) to obtain
16y=-16
We divide through by 16
Putting the value of y into eqn(2)
Adding 2to both sides
Dividing through by 2
Hence, (x, y)=(3,-1)
