The sum of 2 numbders are 21 the 2nd number is six times the first number work out the two numbers

3, 18

Step-by-step explanation:

To write an equation or an expression, define the variables.

x is the first number.

6x is the second number since it is 6 times the first.

Add the expressions together to 21 to solve.

x + 6x = 21

7x = 21

x=3

The first number is 3. The second is 6*3 = 18.

Man this reminds me of 6th grade. Basically all you have to do is combine all the like terms. So you see things like 2x^2, 30y, -x, stuff like that. All you have to do is match it. Add all the Ys together, all tue Xs together, and X^2s together. Make sure to NOT combine X^s with X
