Gemma Nunez · Answer 1

You add the one with the variables then subtract the one without the variables to 21 and divide that by the number with the variables and that’s what equals X

Casey · Answer 2

Like terms are 6x and 7x, 8 and 21 are like terms

subtract 8 from both sides, to make both sets of like terms on opposite sides

6x+7x=21-8

13x=13

x=1
