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

The larger of two numbers is 4 more than 2 times the smaller number. If the sum of the two numbers is 28, what is the larger num
Musya8 [376]

Answer:

The larger number is 20.

Step-by-step explanation:

Let x and y be the two numbers.

y = 2x + 4

x + y = 28

So x + 2x + 4 = 28

3x = 24

x = 8

y = 20

6th grade math ! help me please :)
malfutka [58]
1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.

2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.

3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.

Hope this helps!!!
