Answer:
substitution method is tricky until u get the hang of it. 6y=x so 3x-8y=-50 can be rewritten as 3(6y)-8y=-50.
Step-by-step explanation:
3x-8y=-50.........(1)
6y= x ..............(2)
<u>Substituting x = 6y in (1)</u>
3(6y) - 8y = -50
<u>multiply 3(6y)</u>
18y - 8y = -50
<u>subtract 8y from 18y</u>
10y = -50
<u>divide to get y alone</u>
y = -50/10
y = -5
<u>now substitute. you know what y is. 6y=x / 6(-5)=x</u>
<u>solve :)
</u>
6y = x
6(-5) = x
-30 = x
x = -30
Answer:
A) y= 5x - 3
Step-by-step explanation:
(5 • x) - 3 = y
Problem Solving:
5 • -6 = -30 - 3 = -33
5 • 3 = 15 - 3 = 12
5 • 9 = 45 - 3 = 42
5 • -4 = -20 - 3 = -23
5 • -5 = -25 - 3 = -28
Answer:
See below.
Step-by-step explanation:
10-n≤4+3n
-10 -10
-n≤-6+3n
-3n -3n
-4n≤-6
/-4 /-4
n≥1.5
-hope it helps
(1/8)+(1/8)=(2/8)*2=(4/16)
(15/16)-(4/16)=(11/16)
I hope this helped.
