The problem using elimination/substitution methods what is the solution set to 3x -2y =-4 and 5x=2y the choices
a)(2,-5)
b)(-2,-5)
c)(2,5)
d)(-2,5)
Please, Please, Please, HELP!
3x-2y=-4
-5x +2y=0
add the equations, solve for x. That makes it a or c. Put that answer in the second equation
To solve the system of equations using elimination/substitution method, let's start by adding the two equations together:
3x - 2y = -4
+ (-5x + 2y) = 0
----------------
-2x = -4
Now we solve for x by dividing both sides of the equation by -2:
-2x / -2 = -4 / -2
x = 2
Next, we substitute the value of x into one of the original equations. Let's use 5x = 2y:
5(2) = 2y
10 = 2y
y = 10 / 2
y = 5
So the solution for x and y is (2, 5).
Comparing this solution with the choices given, we can see that the correct answer is (c) (2, 5).
