Question

Solve the following system of equations using the substitution method.

​
​ x=2y
2x+5y=9
​
x=
and
​ y=

Answer 1

x=2y
2x+5y=9

substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2

your answer is: x=2
y=1

Answer 2
