Solve the system of equations by substitution

====================================.

`\large \sf \underline{Answer:}`

x = - 5y + 4

====================================

`\large \sf \underline{Explanation:}`

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)
