27x-8=5x+29 Get the x's on one side and the numbers on the other 22x=37 Divide both sides by 22 x=37/22 If you change it to a decimal, it is a very long one! It's best to leave it is an improper fraction
(5x - 2)(x - 5)
(5x - 4)(2x + 7)
20x^2 + 27x + 9 = 0 20x^2 + 15x +12x + 9 = 0 5x(4x + 3) + 3(4x + 3) = 0 (5x + 3)(4x + 3) = 0 So either (5x + 3) = 0 which yields x = -3/5 or (4x + 3) = 0 which yields x = -3/4

Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
5x plus 3 does equal 3 plus 5x; commutative law.
5*4+3*3 = 29
What is the answer to 2x - 5x plus 6.3 equals -14.4?
It works out that they intersect at: (4, -7)
(4, -7)
x=6
8x-7 plus 2x equals 6 plus 5x plus 2?
