In the first one you can use substitution
2x-3y = 26 2x-3(5x) = 26 ... replace y with 5x (works because y = 5x is given as the first equation) 2x-15x = 26 -13x = 26 x = ??
-2
yes

now plug that into any equation with x & y in it, then solve for y the easiest is y = 5x
-2y/-2 =-5/-2=2?
for -5 i mean 5

1)substitute x= -2 in y=5x y= 5*(-2) y= -10
2) 2x +5y=14 -----I x-3y=4-----------II multiply equation II with 2 and sutract from eq I you will get ,y=6/11
substitute y= 6/11,in equation II x-3*6/11=4 x-18/11=4 x= 4+18/11 x= (44+18)/11 x= 62/11
are u there
