let x be the number of green apples 4x be the number of red apples solution: x + 4x = 50 5x = 50 x = 10 10- number of green apples 4(10)= 40 -number of red apples.

for the first question: x=4y+5 7(4y=5)-2y=35 28y+35-2y=35 26y=35-35 y=0 for x: x-4y=5 (substitute) x-o=5 x=5 (5,0) if you want to check your answer just substitue it to any of the given linear equations. Goodluck!

8x+4y=36 4y=36-8x/4 y=9-8x 2x+y=9 2x+9-8x=9 6x=9-9 x=0 8x+4y=36 8(0)+4y=36 4y=36/4 y=9 (0,9)
