3x + 2y = 11
 
y = 5x-1
 For this case, the first thing you should do is replace the value of y in the first equation.
 We have then:
 3x + 2 (5x-1) = 11
 We rewrite:
 3x + 10x-2 = 11
 3x + 10x = 11 + 2
 3x + 10x = 13
 We clear x:
 13x = 13
 x = 13/13
 x = 1
 We now substitute the value of x in expression 2:
 y = 5 (1) -1
 y = 5-1
 y = 4

 Answer:
 The solution to the system of equations is:
 x = 1
 y = 4

6/10+6/100= how do i do this problem
olya-2409 [2.1K]

Answer:

0.66

Step-by-step explanation:

As division is always done before addition you would divide the 6 by 10 and then divide the 6 by 100. 6 divided by 10 is equal to 0.6 as you move the decimal point to the left once. 6 divided by 100 is equal to 0.06 as you move the decimal point to the left twice. Addition is always done after division so you would add 0.6 and 0.06 together. This will give you 0.66 as your answer.
