Solve: 5x – (7x + 4) = 3(x + 5) + 4(5 – 2x) Hint: Distribute everything first, then combine like terms next.

Step 1. Remove parenthesis.

Step 2: Simplify the left side.

Step 3: Expand.

Step 4: Simplify the right side.

Step 5: Add 4 to both sides.

Step 6: Simplify.

Step 7: Add 5x to both sides.

Step 8: Simplify.

Step 9: Divide both sides by 3

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
