Answer:
u put the algebraic like terms together whether they add or subtract each other
Let’s make an equation
Let’s say x = amount of years after
Smith = 8, mother = 42
3(8 + x) = 42 + x
24 + 3x = 42 + x
2x = 18, x = 9
Solution: after 9 years
5.5x+180=455
5.5x=275
The answer is X=50
The answer to this is 8.6 repeating
700/12 equals 58 and 1/3.
