Question

solve using the substitution method.
3+4y=-10
x=10-8y

Answer 1

put x=4-6y in first eqn,
2(4-6y) +3y =12
8-12y +3y =12
8-9y=12
9y=-4
y= -4/9
we know, x=4-6y
putting y=-4/9 we get, x= 4 - 6(-4/9) = 4 - 2(-4/3) = 4 + 8/3 = 20/3
Ans. x=20/3 y=-4/9

Answer 2

is that an ordered pair

Answer 3

was it checked

Answer 4

@mizzkuntry

To check put the values of x in the orignal question and check if


L.H.S=R.H.S

Answer 5

solve using the substitution method. 3+4y=-10 x=10-8y

Answer 6

has to be simplified
