Sagot :
Answer:
14, 21, 28
Step-by-step explanation:
2x + 3x + 4x = 63
Add like terms
9x = 63
Divide both sides by 9
9x/9 = 63/9
x = 7
Solve for each side by substituting in for x
2x = 2(7) = 14
3x = 3(7) = 21
4x = 4(7) = 28
To check if it is correct, add the three answers together.
14 + 21 + 28 = 63
