Question

Is -2 the solution of 5+x =7? Give reason for your answer

Answer 1

5+x=7
x=7-5
x=2 is the solution not -2
so -2 is not solution

Answer 2

- 2 is not the solution for the given linear equation.

because solving for the ' x ' value gives u x value as

x = 7 -5 = 2

therefore, 2 is the solution for given linear eqation and not -2
