Question

Solve by elimination method.
3x -7y+10=0
1y-2x-3=0​

Answer 1

Answer:

Given equations-

3x-7y+10=0 - eq.1

y-2x-3=0 》-2x+y-3=0 - eq.2

Multiplying eq.2 by 7-

-14x+7y-21=0 - eq.3

Adding eq.1 and eq.3-

3x-7y+10=0

-14x+7y-21=0

___________

-11x-11=0

》-11(x+1)=0

》x+1=0

》x= -1

Putting x= -1 in eq.2-

-2(-1)+y-3=0

》2+y-3=0

》y-1=0

》y=1

Hence value of x is -1 and value of y is 1.
