Shon bought 50 apples. he bought 4 times as many red apples as green apples, how many red apples did he buy?

X+4x=50 5x=50 x=10 4*10=40 So he bought 40 red apples

50=total

4 times as many red as green

r=red apples

g=green apples

bought 4 times as many r as green

this means

r is 4 times of g

r=4 times g

r=4g

total=r+g=50

r+g=50

subsitute 4g for r

4g+g=50

5g=50

divide by 5

g=10

subsitute

r=4g

r=4 (10)

r=40

there wer 40 red apples
