Answer:
Step-by-step explanation:
14x - y = -1
14x = y -1
14x +1 = y
Substitute into other problem:
3x + 2(14x +1) =13
3x + (28x + 2) = 13
31x + 2 = 13
31x = 11
x = 11/31
Answer:
x= 11/31 and y=185/31
Step-by-step explanation:
Solve for y in 14x-y=-1 and get y=1+14x
substitute and get 31x+2=13and then
solve for x in 31x+2=13 and get x=11/31
then substitute x=11/31 into y= 1+14x and
y = 185/31
