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

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

4 + 5 7/9= 9 7/9

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
