Question

Solve the system of equations. 2x + 4y = 36 
                                                       10y = 5

anonymous · Answer

solve for y , in this case y=1/2 ( second equation) , later replaces in the first equation.

anonymous · Answer

multiply 2?

anonymous · Answer

in the second equation how 10y=5 , later y=5/10 
=1/2 ,you  have the value of y and you can replacein  the first equation and get x

im confused..can you please show me

ledah · Answer

I believe he's suggesting the substitution method.

anonymous · Answer

2x + 4y = 36 .....A
10y = 5.....B
use equation B to get the value of y 
y=5/10
y=1/2 place the value of y in equation A
2x+4(1/2)=36
2x+2=36
2x=36-2
2x=34
x=34/2
x=17

anonymous · Answer

so you get x=17 and y=1/2 
or (17,1/2)
