Question

Which expression would be easier to substitute into the other​ equation, in order to solve this​ problem? Explain your reasoning.
x=3y-2
x+3y=4

Answer 1

Answer:

x=3y-2 substitute is easier to solve the equation

Step-by-step explanation:

given x=3y-2.............(1)

x+3y=4................(2)

put x=3y-2 in equation (2)

3y-2+3y=4

6y-2=4

+2

6y=6

y=1

x=3y-2

x=3(1)-2=1

x=3y-2 substitute is easier to solve the equation answer
