Question

solve the equation 15x-6y= 30 ; 17x + 10y = 118

Answer 1

Answer:

x=4

y=5

Step-by-step explanation:

15x-6y=30..............equation 1

17x+10y=118........... equation 2

we have

equation 1 =} 15x-6y=30

=}(15x-6y)×5/3=30×5/3. {multiplying both sides by 5/3}

=}25x-10y=50

now..adding both the equation 1 and 2 we have

25x-10y=50

17x+10y=118

________________

42x + 0 = 168

x=168/42=4

now x=4 so.

we can fetch the value of y by putting the value of x in any of the two equation.

Answer 2

here's the answer
