To prove that the value of x = 7, the equation to use will be 7y = 8x - 14
From the information given, we are given the equation that states that:
7y = 8x - 14
where, y = 6
In this case, we've to put the value of y into the equation and this will be:
7y = 8x - 14
7(6) = 8x - 14
Collect like terms.
42 = 8x - 14.
8x = 42 + 14
8x = 56
x = 56/8
x = 7
Therefore, it has been proven that x = 7
