Answer:
11x.
Step-by-step explanation:
Combine like terms, they are alike because they share the same variable. Add x with 4x which is 5x, or you could do this. x+ x+x+x+x= 5x. 5x means you have 5 x's. Then combine 5x with 6x which is 11x. Hope this helps!
11x
You can add all the coefficients together:
1+4+6 = 11
B) 5(-3) either way its telling you to multiply 5 by -3
5(2x+3) = 85
10x + 15 = 85
x = (85 - 15)/10
x = 7
