2x + 3y = 4
2x= 7y + 24

Let's solve for x.

2x+3y=4

Step 1: Add -3y to both sides.

2x+3y+−3y=4+−3y

2x=−3y+4

Step 2: Divide both sides by 2.

2x/2

=−3y+4/2

x=−3/2y+2

x=−3/2y+2

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
