Please solve this question by using the strategy Elimination Method or Solve By Substitution. This is the math equation: 1/2x+y=15 and -x-1/3y=-6 2nd Question: 5/6x+1/3y=0 and 1/2x-2/3y=3

First pair of equations :

Multiply 2 to equation (i), we get

By Elimination Method, Add (i) and (ii) (term with x eliminate), we get

put y= 14.4 in (iii), we get

hence, x=1.2 and y =14.4

Second pair of equations :

Multiply 2 to equation (i), we get

Elimination Method, Add (i) and (ii) (term with y eliminate) , we get

put   in (i), we get

hence,   and .

step-by-stp

the correct answer is the section c
