5x over 4 = 3 + 3 over 4 = 15 over 4 5x over 4 = 15 over 4 times both sides by 4 5x = 15 divide both sides by 5 x = 3
No, the solution of x = 4 will not be greater than nor less than 4.
If x - (-15) = 11 then x = -4.
What is the solution set of 2x2 + x = 15

(2, 3) is a solution only if it satisfies the equation. x + 5y = 4 (2) + 5(3) =? 4 2 + 15 =? 4 17 = 4 False Therefore, (2, 3) is not a solution to the given equation.
what the solution to this equation x+15=28 If you mean: x+15 = 28 then the value of x works out as 13

x/4 - 4 = x/4 4x/4 - 4 x 4 = x x - 16 = x 0 = 16 There is no solution to the equation.
x-4<5
3x2 + 4x - 15 = 0, solve by using the quadratic formula. a = 3, b = 4, c = -15 x = [-b ± √(b2 - 4ac)]/(2a) x = [-4 ± √(42 - 4*3*-15)]/(2*3) = [-4 ± √(16 + 180)]/6 = (-4 ± √(196)/6 = (-4 ± 17)/6 x = (-4 +17)/6 = 13/6 or x = (-4 - 17)/6 = -21/6 = -7/2 The solution set: {-7/2, 13/6}.
5x over 4 = 3 + 3 over 4 = 15 over 4 5x over 4 = 15 over 4 times both sides by 4 5x = 15 divide both sides by 5 x = 3
If: 4x = x+15 Then: x = 5
4 x 15 x 25 = 1,500.
