Question

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

Answer 1

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

Answer 2

multiply 2?

Answer 3

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

Answer 4

im confused..can you please show me

Answer 5

I believe he's suggesting the substitution method.

Answer 6

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

Answer 7

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