Six less than 2 times a number is 50. What is the number?

Sagot :

sia70

Answer:

a + b = 50 (Two numbers total 50)

b = a - 6 (one number is 6 less than the other)

Since we have a value, we can use the substitution metod:

a + a - 6 = 50

Simplify:

2a - 6 = 50

From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.

2(a) -6= 50

2a-6= 50

six goes and adds to 50 on the other side

2a = 56

divide both sides by 2

a= 28

final answer 28
