7X - 1 = 2X + 2
subtract 2X from each side
7X - 2X - 1 = 2X - 2X + 2
5X - 1 = 2
add 1 to each side
5X - 1 + 1 = 2 + 1
5X = 3
divide both sides integers by 5
(5/5)X = 3/5
X = 3/5
--------------check in original equation
7(3/5) - 1 = 2(3/5) + 2
21/5 - 1 = 6/5 + 2 (1 = 5/5 and 2 = 10/5 )
21/5 - 5/5 = 6/5 + 10/5
16/5 = 16/5
----------------------checks
x = -5
2x + 3 = 72x = 4x = 2
Not sure what you mean; that equation certainly has a solution.
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
x = 3 and y = 2
2x plus 3y
X = 6
x=2
x = 0
x = -5
x=-2
The answer is (3.5)2 plus (4)2 equals 410.
2x + 3 = 72x = 4x = 2
Not sure what you mean; that equation certainly has a solution.
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
1 solution
The solution is: x = 1 and y = -1
