Question

2x - 15 ≤ 5 pls help

Answer 1

$2x - 15 \leqslant 5 \\ 2x \leqslant 20 \\ x \leqslant 10$

Interval Notation: x ε ( -∞ , 10 ]

Answer 2

$\Huge\boxed{x\leq10}$

To solve for $x$, you need to isolate it on one side of the equation.

Start by adding $15$ to both sides.

$\begin{aligned}2x-15+15&\leq5+15\\2x&\leq20\end{aligned}$

Now, divide both sides by $2$ for the final answer.

$\begin{aligned}\frac{2x}{2}&\leq\frac{20}{2}\\x&\leq10\end{aligned}$
