To solve the equation 8x + 7x = 90, you need to combine the like terms on the left side of the equation.
8x + 7x can be simplified to 15x.
So the equation becomes 15x = 90.
To find the value of x, you need to isolate x on one side of the equation. In this case, you can do that by dividing both sides of the equation by 15.
Dividing both sides by 15, you get:
(15x) / 15 = 90 / 15
Simplifying, you get:
x = 6
So the correct answer is x = 6.
Now, to check if your division of 90 by 15 is correct, you can calculate it.
Dividing 90 by 15, you get:
90 / 15 = 6
So yes, your calculation is correct.
