Step-by-step explanation:
divide the first equation by 5
7x+5y=46......(3)
now divide the second equation by 2
5x+7y=50.......(4)
now add the the equations 3 and 4 and subtract them consecutively
when add
12x+12y=96
2x+2y=16....(5)
when subtract
2x-2y=-4....(6)
now add 5 and 6 equation
4x=12
X=3
putting values in 2cond equation
2(3)-2y=-4
6+4=2y
10/2=y
5=y
This is a method which u can use in higher classes also.
Although here it is not required but still u will get to know other method to solve similar equations with Big values.
