The work of a student trying to solve the equation 4(2x − 1) = 11 + 3x + 5 is shown below: Step 1: 4(2x − 1) = 11 + 3x + 5 Step 2: 8x − 4 = 16 + 3x Step 3: 8x + 3x = 16 − 4 Step 4: 11x = 24 Step 5: x = 2.18 In which step did the student first make an error and what is the correct step?

Respuesta :

In step three the prblem was incorrect. this is because you have to add four from both sides leading to 8x=20+3x then you have to subtract 3x which is 5x=20. divinding both sides by 5 is:

In step 3, step 4 and step 5 they made a mistake.

What is Linear Equation?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0.

Here, steps done by students are as follows:

Step 1: 4(2x-1) = 11 + 3x + 5

Step 2: 8x - 4 = 3x + 16

Step 3: 8x - 3x = 16 + 4

Step 4: 5x = 20

Step 5: x = 4

Thus, In step 3, step 4 and step 5 they made a mistake.
