Question

8,75 × x + 1,25 × x = 20

Answer 1

\(\left(8,75+1,25\right)\times x=20\\ 10\times x=20\\ x=20:10\\ x=2\)

Answer 2

8,75 × x + 1,25 × x = 20

=X x(8,75+1,25)=20

X x 10=20

       X=20:10

      X=2

Answer 3

8,75 x X + 1,25 x X = 20

( 8,75 + 1,25 ) x X = 20

10 x X = 20

X = 20 : 10

X = 2
