Question

Solve the system of equations by the substitution method.
X + 8y = 21
3x + 5y = 6

Answer 1

Explanation:

the first one if you are solving for x it will be x=21-8y

if you are solving for y it will be y =21/8 - x/8

the second one will be if you are solving for x x = 2 -5y/3

solving for y is y=6/5-3x/5
