Question

Solve 12x - 4y = 3 and 8x + 4y = 7 simultaneously.​

Answer 1

Step-by-step explanation:

Spirogyra, (genus Spirogyra), any member of a genus of some 400 species of free-floating green algae (division Chlorophyta) found in freshwater environments around the world. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells.

Answer 2

Answer:

x=1/2 and y=3/4

Step-by-step explanation:

we have 2 equations here,

No.1=12x-4y=3

No.2=8x+4y=7

Adding equation 1 and 2 we get,

20x=10

x=1/2

Putting this value of x in equation 2

8*1/2+4y=7

4+4y=7

4y=3

y=3/4

Hope it helps!
