6x plus 3y when x equals 5 and y equals -4?
30 - 12 = 18
X2 plus 6x plus 9 equals 81?
x2 + 6x + 9 = 81 x2 + 6x = 72 x2 + 6x - 72 = 0 (x+12)(x-6) = 0 x= -12, 6 (two solutions)
What is 9x plus 8 equals 6x plus 20?
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
How do you write a situation 6x plus 2 equals 14?
