5×=15+10y,3×+7y=31 it's for tomorrow pls​
Katarina [22]

Answer:

x = 6.39, y = 1.69 is the solution of the given equation system.

Step-by-step explanation:

Here, the given set of equation is:

5 x = 15 + 10 y  ⇒ 5 x - 10 y = 15   ...... (1)

3 x +7 y = 31   ............. (2)

Now, the coefficient of x in first equation id 5 and in second  is 3.

So, MULTIPLY (1) with 3 and (2) with -5 , we get:

15 x - 30 y = 45

-15 x- 35 y = -155

<u>ADD BOTH EQUATIONS ,</u> we get:

15 x - 30 y  -15 x- 35 y = 45 - 155

or, -65 y  = -110

or, y = 110/65 = 1.69

Put y  = 1.69 in 3 x +7 y = 31 , we get:

3(x) +  7 (1.69) =31

⇒ 3 x = 19.17 or x = 6.39

Hence, x = 6.39, y = 1.69 is the solution of the given equation system

tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into  x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)
