Question

10х - 3 = 8х + 39 ________________​

Answer 1

10x-8x=3+39
2x=42
x=42:2
21

Answer 2

To solve the equation 10x - 3 = 8x + 39, follow these steps:

Step 1: Get all the x terms on one side of the equation and constants on the other side. Subtract 8x from both sides of the equation: 10x - 8x - 3 = 8x - 8x + 39

Simplified: 2x - 3 = 39

Step 2: Now, get rid of the constant term on the left side of the equation. Add 3 to both sides: 2x - 3 + 3 = 39 + 3

Simplified: 2x = 42

Step 3: Finally, isolate x by dividing both sides by the coefficient of x, which is 2: 2x / 2 = 42 / 2

Simplified: x = 21

So, the solution to the equation is x = 21.
