Solve x - 7 - 9 equals -3?
x - 7 - 9 = -3x - 16 = -3x = 13
What are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
What is the solution of 2x plus 7 equals 5x plus 16?
2X + 7 = 5X + 16 subtract 2X from both sides 7 = 3X + 16 subtract 16 from both sides -9 = 3X divide both sides by 3 -3 = X check 2(-3) + 7 = 5(-3) + 16 1 = 1 checks
Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
5x plus 7 equals 3x-21?
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
Solve x - 7 - 9 equals -3?
x - 7 - 9 = -3x - 16 = -3x = 13
What are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
What is the solution of 2x plus 7 equals 5x plus 16?
2X + 7 = 5X + 16 subtract 2X from both sides 7 = 3X + 16 subtract 16 from both sides -9 = 3X divide both sides by 3 -3 = X check 2(-3) + 7 = 5(-3) + 16 1 = 1 checks
How do you factor this trinominal 9x2 42x 49?
If that's +42x + 49, the answer is (3x + 7)(3x + 7) or (3x + 7)2 If that's -42x + 49, the answer is (3x - 7)(3x - 7) or (3x - 7)2
How do you solve 7x plus 4 equals 3x plus 7?
(7x + 4) = (3x + 7) Subtract (3x + 4) from both sides of the equation. (7x + 4) - 3x - 4 = (3x + 7) - 3x - 4 4x = 3 x = 3/4 Check: (7x + 4) = 7 (3/4) + 4 = (21/4) + 4 = (21/4) + (16/4) = 37/4 (3x + 7) = 3 (3/4) + 7 = (9/4) + 7 = (9/4) + (28/4) = 37/4 Yay.
Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
What is the area of a square whose side measures 3x-4?
7
What is 3x plus 7?
=3x+7
3x - 2 plus 5 equals 16?
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
What is the answer to 3x plus 7 equals 4x?
3x+7=4x 7=4x-3x 7=x
What is 3x squared -22x -16 when factored?
3x² - 22x - 16 = (3x + 2)(x - 8)
What are the solutions to the simultaneous equations of 3x -5y equals 16 and xy equals 7 showing work?
If: 3x-5y = 16 then -5y = 16-3x => y = -3.2+0.6x by dividing all terme by -5 If: xy = 7 then x(-3.2+0.6x) = 7 => -3.2x+0.6x2 -7 = 0 Solving the quadratic equation: x = 7 or x = -5/3 Solutions of the equations by substitution are: x = 7, y = 1 and x = -5/3, y = -21/5
