-5x=y+2
2(2x-1)=3-3y
What is the solution (x, y) to the system of equations above?
1 answer:
(-1, 3)
Step-by-step explanation:
1st step: put x and y together
-5x = y + 2
5x + y = -2
2 × (2x - 1) = 3 - 3y
4x - 2 = 3 - 3y
4x + 3y = 5
2nd step: make the one similar (x or y)
5x + y = -2 ×(+3)
4x + 3y = 5 ×( -1)
15x + 3y = -6
-4x - 3y = -5
3rd step: collection process
15x + 3y = -6
-4x - 3y = -5
11x = -11
x = -1
The last step: write -1 instead of x in any equation
-5x = y + 2
-5×(-1) = y + 2
5 = y + 2
y = 3
The answer is ( -1, 3)
