commutative property
The Aswer is 50 okay
9x+27 = -81 9x = -81-27 9x = -108 x = -12
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
8x + 33 = 7x + 27 Subtract 7x from both sides: x + 33 = 27 Subtract 33 from both sides: x = -6
x + 2y = 27 2x - y = 19 y = 2x - 19 x + 2(2x - 19) = 27 x + 4x - 38 = 27 5x = 65 x = 13 y = 2(13) - 19 y = 7
It is an incorrect equation.
The commutative property of addition.
yeah, it's equal. This is an example of the Commutative Property of Addition. Think Commute means moving around. So the 27 can be first, or the 6 first, when adding.
Falsehood or mistakes or typographic error.
9(10+3)
please explain further. because 22+272 equals 294... not 227
16 plus 27 equals 43.
55 + 27 + 65 = 147
27 + 20 = 47
27
