if 5x=-20 then it would be

- 20 + 2 - 2 = - 18 - 2
adding 2 and subtracting 2 they cancel out so its

- 20 = - 18 - 2
and if you subtract 2 from negative 18 it is negative 20 so it is true

Cancel −2 on both sides

5x+2=−18

Subtract 2 from both sides

5x=−18−2

Simplify −18 −2 to −20

5x=−20

divide both sides by 5

x=−20/5

simplify 20/5 to 4

x=−4

its false
