It is a linear equation in a single variable, w.
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
Negative 4 minus positive 15 = negative 19
x= Negative 4
It equals positive seven.
19
4.
If: n--3 = -4 Then: n = -7
-4 - 1 = -4 + (-1) = -5
-10 - 4 = -14
It is: 2-4 = -2
The answer to the math problem of 18 minus 4x equals negative 2 is x equals 5.
x = 4 and y = 7
