Yes and it works out that x = 3 and y = 4
(2,-2)
2x-3y=13
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4

10x 2x divide 2x equals?
If that's -5x, the answer is (x - 3)(2x + 1) x = 3, -1/2 If that's +5x, the answer is (x + 3)(2x - 1) x = -3, 1/2
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
Solving by the elimination method gives: x = 3 and y = 2

y=16 x= -4
If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
