x=3.5

Answer 2

Если преобразовать, то:
$2x*7-4=14x-4$

Если уравнение, то:
$2x*7-4$
$14x-4=0$
$14x=4$
$x=\frac{4}{14}=\frac{2}{7}$

Answer 3

Sure, I can help you with that!

To solve the expression 2x * 7 - 4, follow these steps:

1. Multiply 2x by 7. 2x * 7 = 14x

2. Subtract 4 from the result. 14x - 4

So, the final expression is 14x - 4. If you have a specific value for 'x', you can substitute it into the expression to find the result. If 'x' is still a variable, then the expression remains as 14x - 4.
