Question 129875This question is from textbook intermediate algebra
: Solve the system of equations using the substitution method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is “no solution” or “infinitely many solutions.”
-7x + y = 4
2x + 8y = 0

adding 7x to the first equation __ y=7x+4

substituting into second equation __ 2x+8(7x+4)=0 __ 2x+56x+32=0 __ 58x=-32

substitute value of x into y=7x+4 to find y
