For what value of x is the expression –4x – 8 equivalent to –9x –1?
Alexeev081 [22]

The value of x where the expression –4x – 8 will be equivalent to –9x –1 will be 7/13.

<h3>How to calculate the value?</h3>

It should be noted that we are simply to find the value of x where the expression –4x – 8 will be equivalent to –9x –1.

This will be:

= +4x - 8 = -9x - 1.

4x + 9x = -1 + 8

13x = 7

Divide

x = 7/13

The value is 7/13.
