Part 1: Explain, in complete sentences, how you would use the substitution method to solve the following system of equations.

Part 2: Provide the solution to the system

x + 5y = 3
2x + 9y = 4

anonymous · Answer

x = 3 - 5y

2(3 - 5y) + 9y = 4
6 - 10y +9y = 4
2 = y

x = 3 - 5(2)
x = -7

anonymous · Answer

solve the first equation for x via 
$$x=3-5y$$
substitute 
$$3-5y$$ for x in the second equation and write 
$$2(3-5y)+9y=4$$ now you have on variable and one equation.  solve for y and then substitute back into either equation to solve for x

enough words for you?
