Answer:
11
Step-by-step explanation:
Let's call the white marbles w and the red marbles r. We can write:
w + r = 16 (1)
w = 3r - 4 (2)
3r - 4 + r = 16 (3) (Substitute (2) into (1))
4r = 20 (simplify)
r = 5 (divide by 4) which means w = 16 - 5 = 11
Answer:
5 i believe correct me if im wrong
Step-by-step explanation:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
