Answer:
3.6
Step-by-step explanation:
6r-5 = -3(r-2)
6r-5 = -3r+6
6r-3r = 3r
6+5 = 11
11/3 = 3.6
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
