Answer:

x = -3

Step-by-step explanation:

y = 7

y = -2x+1

substitute for y

7 = -2x+1

subtract 1 from each side

6 = -2x

divide both sides by -2

6/-2 = x

x = -3

Finish solving the system of equations –9.5x – 2.5y = –4.3 and 7x + 2.5y = 0.8 using the linear combination method. 1. Determine
mars1129 [50]

Answer:

Step-by-step explanation:

The given equations are:

-9.5x – 2.5y = –4.3                    (1)

and 7x + 2.5y = 0.8                  (2)

Adding equation (1) and (2) together, we get

-9.5x-2.5y+7x+2.5y=-4.3+0.8

⇒-2.5x=-3.5

⇒x=1.4

Now, substitute the value of x=1.4 in equation (1),

-9.5(1.4)-2.5y=-4.3

⇒-13.3-2.5y=-4.3

⇒-13.3+4.3=2.5y

⇒-9=2.5y

⇒y=-3.6

Thus, the value of x and y are 1.4 and -3.6 respectively.
