Solve by using the substitution method. (Please keep fractions as they are, don't convert to decimal.)
y= 1/7x + 3
x  7y= 4

PsyDAG,
Substitute 1/7x+3 for y in second equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
