a+b+c+d+e = 30 (i)
c+e = 14 (ii)
d+b = 1 (iii)
a = 2b-1 (iv)
a+c = 10 (v)
By (i)-(ii)-(iii): a = 15
then, by (iv): b = 8
and by (v): c = -5
Also, b = 8 so by (iii): d = -7
and then by (i), e = 19
n = 3/2, n = 2

They are identities because they are true for ALL values of w and x.
900 plus 900 equals 1800. When adding two numbers together, you are essentially combining their values to find the total sum. In this case, adding 900 and 900 results in 1800, as each 900 contributes its full value to the final sum.
x=-3y=4
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.
Two plus eleven = thirteen.

The values are: x = -6 and y = 10
Decomposition into decimal digits (or separating out into place values).
199+803 = 1002
The letters 'y', 'm', 'x' plus 'b' in mathematics mean a specific number in an algebraic equation. The objective is to work out what the values of the letters are.
144 (square the first value and add the product of the two values). In the statement 7 + 6 should = 91, not 63, which would be 7 + 2.
Any two values which total 25
