Answer: x = - 1, y = 5
Step-by-step explanation:
6=4x+2y ... eq 1
-19=4x-3y ... eq 2
Subtracting eq 2 from eq 1
6=4x+2y
-
-19=4x-3y
This gives;
25=5y
divide both sides by 5
y=5
Substituting the value of y in eq 1
6=4x + 2 (5)
6=4x + 10
Subtract 10 from both sides
6-10=4x+10-10
-4=4x+0
-4=4x
Divide both sides by 4
-1=x
Therefore, x = - 1
Verify the values of x and y in either of the equations, Let's use equation 1
6 = 4 (-1) + 2 (5)
6 = - 4 + 10
Hence, X = - 1 and y = 5
