X = -3y + 1

4x - 3y = -11

pls help :

x=-2, y=1

Step-by-step explanation:

Sub x=-3y+1

4(-3y+1)-3y=-11

y=1

then sub y into the first equation

x=-3(1)+1

x=-2

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
