Answer:
Simplified form of given expression 15+12x−5x+4y−7 is 7x + 4y + 8
Step-by-step explanation:
Given expression 15+12x−5x+4y−7
We have to solve the given expression by combining like terms.
Combining like terms is a way in which we add the terms having same variable with same power.
Consider the given expression 15+12x−5x+4y−7
Here, we have two variables x and y
So , 12x and -5x are liek terms so adding them we get, (12-5)x = 7x
Also, 15 and -7 are constants and like terms also, so adding them we get, 15 - 7 = 8
Thus, simplified form of given expression 15+12x−5x+4y−7 is 7x + 4y + 8
