Please help ;-; Solve for the simultaneous equation…. 5x+y=17 X+y=3

Svetach [21]

Given Equation:-

5x+y=17 . . . . . . . . 1
x+y=3 . . . . . . . . . . 2

To find :

value of x
value of y

Solution :

Let's start with equation 2:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

5x+y=17
5x + (3 - x) = 17
5x - x + 3 = 17
4x + 3 = 17
4x = 17 - 3
4x = 14
x = 14/4
x = 7/2
x = 3.5

Now Let's find value of y:

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = 0.5

kamari opens a bank account with 250 five weeks her account balances 800 what was the average rate of change of her account bala

Anettt [7]

The answer is an average rate of change of 110 more dollars in her account per week. You find this by first subtracting the starting amount of 250 from the end amount of 800 that equals 550. then you divide that number by five, the number of weeks, to get the average rate of change.
