Question

The solution of this equation has an error. Which of the following steps has an error?

Step 1: -2x + 8 - 3x = 7
Step2:–5x+8=7
Step3:-5x = 15
Step4:
x = -3

O Step 2

O Step 1

O Step 3

Answer 1

3rd step

Solution:-

$\\ \sf\longmapsto -2x+8-3x=7$

$\\ \sf\longmapsto -2x-3x+8=7$

$\\ \sf\longmapsto -5x+8=7$

$\\ \sf\longmapsto -5x=7-8$

$\\ \sf\longmapsto -5x=-1$

$\\ \sf\longmapsto x=\dfrac{-1}{-5}$

$\\ \sf\longmapsto x=\dfrac{1}{5}$
