Question

Help
solving variables on both sides​

Answer 1

`\\ \sf\bull\dashrightarrow 7x+2=4x+0`

• Any no added with 0 will the number itself.Hence omit zero

`\\ \sf\bull\dashrightarrow 7x+2=4x`

`\\ \sf\bull\dashrightarrow 7x-4x=-2`

`\\ \sf\bull\dashrightarrow 3x=-2`

`\\ \sf\bull\dashrightarrow x=(-2)/(3)`

Answer 2

Explanation:

7x + 2 = 4x + 0

both sides substracted by 2

7x = 4x -2

both sides substracted by 4x

7x-4x = -2

3x = -2

both sides divided by 3

3x/3 = -2/3

=> x = -⅔
