Step-by-step solution for: Linear Equation Worksheets (printable, online, answers, examples)
To solve each of the given linear equations, we will follow a systematic approach: expand, simplify, isolate the variable, and solve for \( x \). Let's go through each equation step by step.
---
1. Expand the parentheses:
\[
5x + 2(2x - 4) = 55
\]
\[
5x + 4x - 8 = 55
\]
2. Combine like terms:
\[
9x - 8 = 55
\]
3. Isolate the term with \( x \):
\[
9x = 55 + 8
\]
\[
9x = 63
\]
4. Solve for \( x \):
\[
x = \frac{63}{9}
\]
\[
x = 7
\]
Solution: \( x = 7 \)
---
