Check whether the value of x=20 is satisfied for the equationx4=6 or not.
For checking whether x=20 is a solution or not for x4=6
Put x=20
LHS=x4=206=103
RHS=6
As, RHS is not equal LHS
Therefore, x=20 does not satisfy equation x4=6
Check whether the value of x=4 satisfied for the equation 20-x=16
Check whether the value of x=4 satisfied for the equation 3x4=6
Check whether the value of x=3 satisfies the equation 6+2x=12 or not.
Check whether the value of x=4 satisfies the equation 12x=2 or not.
If the equation is 4l=20 and the value of variable is l=20 check whether it satisfies the equation or not ?
