19-3x=21+x
Add 3x to both sides.
19-3x+3x=21=x+3x
19=21+4x
Subtract 21 from both sides.
19-21=21+4x-21
-2=4x
Divide both sides by 4.
-1/2=x

Hope this hleped!

Subtract 19 from both sides
-3x=2+x

Subtract x from both sides
-4x=2

Divide both sides by -4
x=-1/2

Final answer: x=-1/2

David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use t

Y_Kistochka [10]

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54
