A positive + A positive = A positive (1+2=3)
A negative + A negative = A negative (-1+(-2)=-3)
Adding a negative is like subtracting a positive (1 + (-2) = -1) this is equal to (1 - 2 = -1)
Adding a positive is like subtracting a negative (-1 + 2 = 1)

Answer:
x = 3
Step-by-step explanation:
7(x + 4) - 7 = 48 - 2x ← distribute parenthesis and simplify left side
7x + 28 - 7 = 48 - 2x
7x + 21 = 48 - 2x ( add 2x to both sides )
9x + 21 = 48 ( subtract 21 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
