What is the solution for 15 equals 5x?
5x = 15 so x = 15/5 = 3
What is the solution to X plus 15 equals 16?
x+15=16x=16-15x=1
What is the solution to the equation below 4x equals x plus 15?
If: 4x = x+15 Then: x = 5
What is the solution of this linear system 3x plus 5y equals -1 2x-5y equals 16?
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
What is the answer to 15 plus X equals 28 X equals what?
x = 13
Which is the solution set for 3x2 plus 4x -15 equals 0?
It is: x = 5/3 and x = -3
What is the solution set of 2x2 x equals 15?
What is the solution set of 2x2 + x = 15
3x2 plus 4x-15 equals 0?
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
What is the solution set for 3x2 plus 4x 15 equals 0?
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}.
What is the solution set of -8x plus x plus 15 equals -7x plus 12?
the empty set.
2x3 plus 3x5- 3x2 equals?
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
Solution set for 2x2-7x-15 equals 0?
Factors: (2x + 3)( x - 5) so x = -1.5 or 5
What is the solution for 15 equals 5x?
5x = 15 so x = 15/5 = 3
