false. because 5plus 3 plus 7 equals, 15, and 15 plus three is not seven
2x + 3 = 72x = 4x = 2
x + 3 = 10Subtract 3 from each side:x = 7
It is an equation and the value of y is 18

-4 + 7 = 3
false. because 5plus 3 plus 7 equals, 15, and 15 plus three is not seven
Associativity and commutativity.
It equals a simple linear equation in 'y'. Its solution is 7/3 .
2x + 3 = 72x = 4x = 2
x + 3 = 10Subtract 3 from each side:x = 7
3m + 11n = 3
It is an equation and the value of y is 18
7
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
x^2+4x+7
It is the equation of a line in 3-dimensional space.
