Answer:
No solution
Explanation:
-3x + 3y = 4
-x + y = 3
Solve the equation for x:
Move the variable to the right side and change its sign
-x + y = 3
-x = 3 - y
Change the signs on both sides of the equation
-x = 3 - y
x = -3 + y
Substitute the given value of x into the equation -3x + 3y = 4
-3x + 3y = 4
x = -3 + y
-3(-3+y)+3y=4
Solve the equation for y
-3(-3+y)+3y=4
y = 0
There is no solution for y.
And since there's no solution for y, the system has no solution.
