Simplify the expression: –2b + 7 – 2a + 5b – 6a

a. –8a+ 3b +7
b. 8a – 3b + 7
c. –4a + 7b + 7
d. 4a – 3b + 7

A. -8a + 3b + 7

Step-by-step explanation: To answer this we have to combine like terms so we have to things being multiplied by a and two things being multiplied by b so we have to combine those to numbers,

So the first number (-2b) is a negative so when we add it to the positive (5b) we get 3b, (-2b + 5b = 3b)

Now onto the a's, both of them are negative so we can add them together then put the negative sign after them, -2a + -6a = -8b,

Finally we have the 7 but it is still just adding 7 to the equation so from what we just did A. -8a + 3b + 7 is the best answer.
