Question

Can someone please help me ASAP

Answer 1

Answer:

A. ( -5.3 , -2.5)

Step-by-step explanation:

Given

x + y = - 7.8 ..........equation 1

y = 2x + 8.1 ............equation 2

Putting equation 2 in equation 1

x + 2x + 8.1 = - 7.8

3x = - 7.8 - 8.1

3x = - 15.9

x = -15.9 / 3

x = -5.3

Now

y = 2 * (-5.3) + 8.1

= - 10.6 + 8.1

= -2.5
