Yes with what ? are u single ?
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
The percent decrease is 20%.
150 - 120 = 30
30 divided by 150 = 0.2
0.2 as a percent is 20
