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

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.
