The value of x in the equation is -7

<h3>What is an algebraic equation?</h3>

An algebraic equation is an expression that consists of numbers, variables with their arithmetic operations.

From the given algebraic equation:

7x - 4 = 3 + 8x

By collecting the like terms, we have:

7x - 8x = 3 + 4

-x = 7

Multiply both sides by (-) sign,

x = - 7
