3 0

Answer:

x = 1

Step-by-step explanation:

-2x + y = 4

y = 2x + 4

2x + 3y = 20

2x + 3(2x + 4) = 20

2x + 6x + 12 = 20

8x + 12 = 20

8x = 8

x = 1

Ganezh [65]

Answer:

Step-by-step explanation:

                              To isolate <em>a</em>, we add -3.75 to both sides.

                                              <em>a</em>-(-3.75)=6.11

                                   <em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>

                                                           <em>a</em>=6.11<em><u>+(-3.75)</u></em>   Simplifying, we get:  

<em>a</em>=2.36
