Step-by-step explanation:
9(x+1) = 25+x
open the bracket
9x + 9 = 25+x
collect like terms
9x-x = 25-9
8x = 16
x = 2
Answer:
9(x + 1) = 25 + x ← distribute parenthesis on left side
9x + 9 = 25 + x ( subtract x from both sides )
8x + 9 = 25 ( subtract 9 from both sides )
8x = 16 ( divide both sides by 8 )
A. 9x-1 B. 14x+29 C. 14x-7
√4 = 2, √36 = 6, √49 = 7
only √2 is irrational!
Answer: z=8
9z-3z=48
6z=48 ⇔ combine like terms
z=8
