the answer is a
w=10
59
This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.
9 plus 7 equals 144. Generally, x plus y = x(x+y).
144 This works if you first add the two digits (ex. 2+3=5), then multiply the first digit by the answer you got (2+5=10).

3x plus -5 equal 7. so x is 4 so 3times 4 is 12-5 will equal 7.
144
144
It equals 24.
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2

5 plus 3 plus 7 does equal 5 plus 7 plus 3; this is an example of the commutative property of addition. Therefore, the statement is true.
9 plus 7 equals 144. Generally, x plus y = x(x+y).
