The equation that has the solution x = 4 is x + 8 = 3x.
Given that,
The x = 4.Based on the given options,
(a) 4x = 20
Now if we put x value in the equation
Put x as 4
So
4x = 20
4(4) = 20
8 = 20
(b)
x ÷ 2 = 8
4 ÷ 2 = 8
2 = 8
(c)
x + 8 = 3x
(4) + 8 = 3(4)
12 = 12
Therefore we can conclude that the equation that has the solution x = 4 is x + 8 = 3x.
