Ответ:
x = 7
Step-by-step explanation:
Substitute y = 4 into the equation and solve for x
8x - 2(4) = 48
8x - 8 = 48 ( add 8 to both sides )
8x = 56 ( divide both sides by 8 )
x = 7
Ответ:
x = 7
Step-by-step explanation:
8x - 2y = 48
y = 4
First, let's substitute y for it's actual value as we know it.
8x - 8 = 48
Next, add 8 on both sides. (When doing these sort of questions you must do the inverse.)
8x = 56
Divide both sides by 8 to get x.
x = 7
Hope this helps and I hope you have a good day!:)
