4. solve by the substitution method\
3x+y=2
x=19-5y or x+5y=19

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++3%5Cx+%2B+1%5Cy+=+2%2C%0D%0A++++1%5Cx+%2B+5%5Cy+=+19+%29%0D%0A++We'll use substitution. After moving 1*y to the right, we get:
3%2Ax+=+2+-+1%2Ay, or x+=+2%2F3+-+1%2Ay%2F3. Substitute that
into another equation:
1%2A%282%2F3+-+1%2Ay%2F3%29+%2B+5%5Cy+=+19 and simplify: So, we know that y=3.92857142857143. Since x+=+2%2F3+-+1%2Ay%2F3, x=-0.642857142857143.

Answer: system%28+x=-0.642857142857143%2C+y=3.92857142857143+%29.
