Question

x-152*3=544                x*3+3280=7450

Answer 1

a)x-152*3=544          b)x*3+3280=7450

x-456=544                x*3=7450 -3280

x=544+456                x*3=4170

x=1000                     x=4710:3

                                x=1570

Answer 2

\(x-152\times3=544\)

\(\Leftrightarrow\)\(x-456=544\)

\(\Leftrightarrow\)\(x=544+456\)

\(\Leftrightarrow\)\(x=1000\)

Answer 3

\(x\times3+3280=7450\)

\(\Leftrightarrow\)\(x\times3=7450-3280\)

\(\Leftrightarrow\)\(x\times3=4170\)

\(\Leftrightarrow\)\(x=4170\div3\)

\(\Leftrightarrow\)\(x=1390\)

Answer 4
