enter answer
question 4
solve and check the equation.
5x - 5 = 20
enter answer

Explanation:

Question 3

Step1: Isolate the term with x

Add 5 to both sides of the equation $8x - 5=11$. So, $8x-5 + 5=11 + 5$, which simplifies to $8x=16$.

Step2: Solve for x

Divide both sides of $8x = 16$ by 8. We get $x=\frac{16}{8}=2$.

Step3: Check the solution

Substitute $x = 2$ into the original equation: $8\times2-5=16 - 5=11$. The left - hand side equals the right - hand side.

Step1: Isolate the term with x

Add 5 to both sides of the equation $5x-5 = 20$. So, $5x-5 + 5=20 + 5$, which simplifies to $5x=25$.

Step2: Solve for x

Divide both sides of $5x = 25$ by 5. We get $x=\frac{25}{5}=5$.

Step3: Check the solution

Substitute $x = 5$ into the original equation: $5\times5-5=25 - 5=20$. The left - hand side equals the right - hand side.

Answer:

$2$
