Answer 3

To solve the equation -2x - 21 = 8x + 59, follow these steps:

Step 1: Combine like terms on both sides of the equation. Add 2x to both sides to get rid of -2x on the left side: -2x - 2x - 21 = 8x + 2x + 59

Simplifying: -4x - 21 = 10x + 59

Step 2: Get all the x terms on one side and the constants on the other side. Subtract 10x from both sides to move the x terms to the left side: -4x - 10x - 21 = 10x - 10x + 59

Simplifying: -14x - 21 = 59

Step 3: Isolate the x term by getting rid of the constant on the left side. Add 21 to both sides: -14x - 21 + 21 = 59 + 21

Simplifying: -14x = 80

Step 4: Solve for x by dividing both sides by -14: x = 80 / -14

Simplifying: x = -40/7

So the solution to the equation is x = -40/7.
