5x+4 is your answer first you do distributive property then you and like terms
Answer: 8=1/2x
Step-by-step explanation:
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!
8x-5=19
+5 on each side
8x=24
Divide by 8 on each side.
X=3
