Question

he work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below: Step 1: 3(2x − 4) = 8 + 2x + 6 Step 2: 5x − 7 = 14 + 2x Step 3: 5x − 2x = 14 + 7 Step 4: 3x = 21 Step 5: x = 7 In which step did the student first make an error and what is the correct step

Answer 1

step 2 is wrong

Explanation:

step 2 is wrong

they added the numbers instead of timesed them

it should b 6x-12=14+2x

if u want to solve this

6x-12=14+2x

4x-12=14

4x=26

x=6.5
