Solve Linear Equation: 3x+4+8x-15=0 Step by Step

To solve the equation $3x + 4 + 8x - 15 = 0$, we begin by combining the terms that involve $x$ and the constant terms:

Step 1: Combine like terms.
The terms involving $x$ are $3x$ and $8x$. Adding these yields:

$11x$

The constant terms are $+4$ and $-15$. Combining these gives:

$+4 - 15 = -11$

Thus, the equation becomes:

$11x - 11 = 0$

Step 2: Solve for $x$.
To isolate $x$, add 11 to both sides of the equation:

$11x - 11 + 11 = 0 + 11$ $11x = 11$

Now, divide both sides by 11:

$x = \frac{11}{11}$ $x = 1$

Therefore, the solution to the equation is $x = 1$.
