Hi Friend !!!
Here is ur answer !!
2x-y = -10
y = 2x+10
7x+3y = 43
7x + 6x+30 = 43
13x = 13
x = 1
2x-y = -10
y = 2+10 = 12
Hope it helps u :-)

x=-10+y/2
7(-10+y/2)+3y=43
-70+7y/2+3y=43
-70+7y+6y/2=43
13y=86+70
y=156/13
y=12
x=-10+y/2
x=-10+12/2
x=11
7(-10+y/2)+3y=43
-70+7y/2+3y=43
-70+7y+6y/2=43
13y=86+70
y=156/13
y=12
x=-10+y/2
x=-10+12/2
x=11
