-2x+7+9x-4
You want to combine terms?
7x + 3
X equal to 3 over 7
To simplify the expression -2x + 7 + 9x - 4, you can combine like terms.
Like terms are terms that have the same variable raised to the same power. In this expression, the like terms are -2x and 9x. The constants 7 and -4 are also like terms.
Combining the like terms, we have:
-2x + 9x + 7 - 4
To combine the x terms, we add their coefficients:
(-2 + 9)x + 7 - 4
Simplifying the x terms, we get:
7x + 7 - 4
Combining the constants, we have:
7x + 3
So, the simplified expression is 7x + 3.
