Chapter 2, Problem 1RP

Solve for x.

$7x-3=-5x-18$

To determine

To calculate: The solution for $x$ from the following expression $7x-3=-5x-18$.

Answer to Problem 1RP

Solution:

The solution for $x$ from the provided expression $7x-3=-5x-18$ is $\underset{\_}{x=-\frac{5}{4}}$.

Explanation of Solution

Calculation:

Consider the expression,

$7x-3=-5x-18$

Combine like terms,

$\begin{array}{l}7x+5x=-18+3\\ 12x=-15\end{array}$

Divide each side of equation by 12,

$x=-\frac{15}{12}$

Simplify,

$x=-\frac{5}{4}$

Hence, the value of $x$ is $-\frac{5}{4}$
