Step-by-step explanation:
x = the money he got for his birthday
x - 12 = $28
x = $40
he got $40 for his birthday.
Answer:
Equation
28 = X - 12
Solve for X
Isolate the X
28+12 = X
40 = X
I believe the first and last choice is correct.
~ hope I'm correct, if not I'm sorry~
The product of x and y would be (8)(-1) = -8. by adding the two equations you get 2x = 16 so x = 8. then y = 7 - x = -1. Therefore xy = -8.
cross ❌ multiply
6x-1=2
6x=2+1
6x=3
divide both sides by 6
x=1/2
