5a + 3 = 7a - 1
add 1 to both sides
5a + 4 = 7a
so 4 = 2a
as 5a + 2a = 7a
4 = 2a = 2 x 2
so a = 2
Check:
then 5a + 3 = 10 + 3 = 13
and 7a - 1 = 14 - 1 = 13
The number is -13.
Five minus 2 does not equal to 4
Minus 25 (5x5=25 if there is one minus then the answer is minus).
2 * (-2) - (-5) = 1
By definition, any number raised to the zero power is "one".
It is minus 20.
