Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o
If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:
7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams
p = 7 * o = 7 * 145 grams = 1015 grams
Result: A pineapple weights 1015 grams and an orange 145 grams.
