Solve the system of equations by substitution
====================================.
[tex]\large \sf \underline{Answer:}[/tex]
x = - 5y + 4
====================================
[tex]\large \sf \underline{Explanation:}[/tex]
x + 5y = 42x + 10y = 8
2(- 5y + 4) + 10y = 8
substituted in the equation for x - 10y - 8 + 10y = 8
distributed
8 = 8
combined like terms 0 = 0(- 10y + 10y)
