2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
x = 3 and y = 2
An equation, solution x = -10
3x + 2 = 3x + 6 This is not possible.
Both of them are equations!The solution is (x, y) = (2, 1).
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
x = 3 and y = 2
An equation, solution x = -10
The solution to 5 = 3x + 2 is found by first subtracting 2:3 = 3x.Then dividing by 3:x = 1.
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
3x + 2 = 3x + 6 This is not possible.
Both of them are equations!The solution is (x, y) = (2, 1).
3x + 6 = 12Subtract 6 from each side:3x = 6Divide each side by 3:x = 2
(2, -1)
Their graphs are.
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
