Answer:
equation: 4x+6=9
x=0.75
Step-by-step explanation:
4x+6=9
subtract 6 from both sides
4x+6-6=9-6
4x=3
divide by 4 on both sides
4x÷4=3÷4
x=0.75
I hope this is good enough:
(x,y) = (r,16)
With this knowledge, plug in r for x, and 16 for y
16 = 2(r) - 4
Isolate the r, add 4 to both sides
16 (+4) = 2r - 4 (+4)
20 = 2r
Divide 2 from both sides
20/2 = 2r/2
r = 20/2
r = 10
hope this helps
