Question

I don’t understand this

Answer 1

x=7

Explanation:

we know that both degrees are equal to each

other so we set (17x-10)=(15x+4)

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

17x−10=15x+4

Step 1: Subtract 15x from both sides.

17x−10−15x=15x+4−15x

2x−10=4

Step 2: Add 10 to both sides.

2x−10+10=4+10

2x=14

Step 3: Divide both sides by 2.

2x

2

=

14
