How do I solve 9.7x+8.2=5.9x-7.

and 15.4x-13.7=14x-17.2

Let's solve your equation step-by-step.

9.7x + 8.2 = 5.9x - 7

Step 1: Subtract 5.9x from both sides.

9.7x + 8.2 - 5.9x = 5.9x

-7 - 5.9x 3.8x + 8.2 = - 7

Step 2: Subtract 8.2 from both sides.

3.8x + 8.2 - 8.2 = - 7 - 8.2

3.8x = - 15.2

Step 3: Divide both sides by 3.8.

3.8x / 3.8 = - 15.2 / 3.8

x = - 4
