y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3

Answer:

Step-by-step explanation:

The two equations are similar, because if you multiply the first one by 3 it will be equal to the second one, so when that happens we say that there are infinite solutions.

Emily and Lily are reading the same copy of the same book for a summer reading assignment.

AnnyKZ [126]

Answer:

Step-by-step explanation:

emily : 16 + 22x....with x being the number of days

Lily : 24 + 18x

16 + 22x = 24 + 18x

22x - 18x = 24 - 16

4x = 8

x = 8/4

x = 2 <==== they will be on the same page in 2 days

16 + 22x = 16 + 22(2) = 16 + 44 = 60

24 + 18x = 24 + 18(2) = 24 + 36 = 60

and they will both be on page 60 <===
