My answer x= -3
Correct.
Thanks
You're welcome.
To solve the equation 7x - 10x = 9, we need to combine like terms on the left side of the equation.
7x - 10x can be simplified to -3x. Therefore, our equation becomes:
-3x = 9
To isolate x, we need to divide both sides of the equation by -3. By dividing both sides by the coefficient of x, we can solve for x:
-3x / -3 = 9 / -3
Simplifying this equation, we get:
x = -3
Therefore, the solution to the equation 7x - 10x = 9 is x = -3.
