5x-2x = 3
3x-28-5x=5x+13 Let us first solve the variables -2x-28=5x+13 Transposing -28 to Right hand side -2x=5x+13+28 -2x=5x+41 Transposing 5x to left hand side -2x-5x=41 -7x=41 equation 1 x=41/-7 x=-41/7 Hence the required answer is -41/7. You can verify it by substituting the value of x in the given equation. If Right hand side is equal to Left hand side the answer is right. Let us verify Substituting the value of x=-41/7 in the given equation1 -7(-41/7)=41 -7 X -41/7 =41 41=41 LHS=RHS Hence Verified
2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
5x - 3 + 2x + 7 = ?7x + 5 = ?
2x2+5x+3 = (2x+3)(x+1) when factored
5x-2x = 3

x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
5x -2x = 3
2x-5x-3 -3x-3 -3(x+1)
2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
2x squared - 5x - 3 = (2x +1)(x -3)
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
5x - 3 + 2x + 7 = ?7x + 5 = ?
2x squared minus 5x minus 3 factored is (2x+1)(x-3).

5x=2x+27 subtract 2x from both sides get get X on only 1 side of the equation. 5x-2x=2x-2x + 27 leaves you with 3x = 27 divide both sides by 3 3x/3 = 27/3 leaves you with x = 9 answer X=9
