Y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
Answer:
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
x = 20 i.e. Alexis
And, Jelani be 40
Step-by-step explanation:
Given that
Jelani has twice as much as Alexis
And, both can added $20
Jelani will have 1.5 times as much on his pass on Alexis
We need to write an equation also the amount does Jelani and Alexis have
So,
Let us assume the alexis be x
And, Jelani be 2x
Now
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
1.5x + 30 = 2x + 20
-0.5x = -10
x = 20 i.e. Alexis
And, Jelani be 40
Answer:
james drove 60 and roger drove 30
Step-by-step explanation:
90/3= 30= roger
90/3=30x2=60= james
james(60)+roger(30)= 90
