Question

Enter the value of C when the expression 21.2x+c is equivalent to 5.3(4x-2.6)

Answer 1

Make the equations equal to each other to find x. 

21.2x+c=5.3(4x-4.6)

Now distribute. 

21.2x+c=21.2x-24.38

So c= -24.38

Answer 2

Make the equations equal to each other to find x. 

21.2x+c=5.3(4x-4.6)

Now distribute. 

21.2x+c=21.2x-24.38

So c= -24.38
