Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?
Answers
The value of x is -1 and value of y is -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are
x+5y=-6...(1)
5x – 3y = -2...(2)
Multiply equation 1 with 5
5x+25y=-30..(3)
Subtract equation 2 and equation 3
5x-3y-5x-25y=-2+30
-28y=28
Divide both sides by 28
y=-1
Now plug in y value in equation 1
x=5-6
x=-1
Hence, the value of x is -1 and value of y is -1.

Dimitri wrote the equations y = 3x and y = x + 3.
Use the drop-down menus to make true statements about the equations and the graph.
Answers
The coordinate point of intersection on the graph will be at (1.5, 4.5)
Given the equations Dimitri wrote expressd as:
y = 3x
y = x + 3
Since they are both y-values, we can equate the right hand side to have:
3x = x + 3
3x - x = 3
2x = 3
x = 3/2
x = 1.5
Get the value of y:
y = 3x
y = 3(1.5
y = 4.5
Hence the coordinate point of intersection on the graph will be at (1.5, 4.5)

A line is represented by the equation y = 3x - 6. Which is a coordinate of a
point that lies on the line?
0 (0,3)
0 (-6,3)
O (2,0)
0 (-3,1)
Answers
Answer:
(2,0)
Step-by-step explanation:
Simply plug in the coordinates. y= 3x - 6, so in this case 0= 3(2) - 6 or 0=0, making the point on the line. If the equation is not true like when using (0,3) and getting 3= -6, then the point is not on the line.
