Does anyone know the answer to this? -15 + 8x = 2x + 3

=3

Step-by-step explanation:

1

Rearrange terms

−15+8=2+3

{\color{#c92786}{-15+8x}}=2x+3−15+8x=2x+3

8−15=2+3

{\color{#c92786}{8x-15}}=2x+38x−15=2x+3

2

Add 

15

1515

 to both sides of the equation

8−15=2+3

8x-15=2x+38x−15=2x+3

8−15+15=2+3+15

8x-15+{\color{#c92786}{15}}=2x+3+{\color{#c92786}{15}}8x−15+15=2x+3+15

Add the numbers

Add the numbers

8=2+18

= 3

Step-by-step explanation:

− 1 5 + 8 = 2 + 3

8 − 1 5= 2 + 3

8 − 1 5 + 15 = 2 + 3 +1 5

8 = 2 + 1 8

8 − 2 = 2 + 1 8 − 2

6 = 1 8

divide both sides by 6

Solution

= 3
