The point (7, 8) is the solution of which of the following systems of equations?
Alex73 [517]

Option 4

<u>V</u><u>e</u><u>r</u><u>i</u><u>f</u><u>i</u><u>c</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u>

\\ \sf\longmapsto x-7y=-49

\\ \sf\longmapsto 7-7(8)=-49

\\ \sf\longmapsto 7-56=-49

\\ \sf\longmapsto -49=-49

And

\\ \sf\longmapsto 10x+9y=142

\\ \sf\longmapsto 10(7)+9(8)=142

\\ \sf\longmapsto 70+72=142

\\ \sf\longmapsto 142+142

Hence verified
