Question

7x+3y=7/6 Y=6x-1 Use the method of substitution to solve

Answer 1

Answer:

x= 1/6

y= 0

Step-by-step explanation:

7x+3(6x-1) = 7/6               Substitute in.

7x+18x-3 = 7/6                 Distributive Property.

25x = 25/6                       Isolate the variable.

x= 1/6                               Divide by 25.

y= 6(1/6)-1                        Substitute in.

y= 1-1                              Multiply.

y= 0                                Subtract.

Answer 2

Answer:

X=1/6 Y=0

Step-by-step explanation:

If Y= 6x-1, substitute Y on the first equation

7x+3(6x-1)=7/6

7x+18x-3=7/6

25x=(7/6)+3

25x=25/6

x=1/6

Then substitute X on the second equation

Y=6(1/6)-1

Y=0
