Answer:
x=2
Step-by-step explanation:
6+8x=6x+10
6+2x=10 Subtract 6 from both sides
2x=4 subtract 6 from both sides
x=2 divide by 2 on both sides
Hope this helps plz mark brainliest :D
Answer: you have to divide each side by 8, not 4. If you divide by 4, you get 2x = 1
The correct answer would be 1/2
Answer:
5 + 2q = 15
Step-by-step explanation:
The perimeter is 4 + 2 + q + (q - 1) = 15.
Add 4 + 2 then subtract the sum from both sides.
q + (q - 1) = 9
This can be simplified further by adding the "q" variables together.
2q - 1 = 9
Add 1 to both sides.
2q = 10
Divide both sides by 2 to isolate q.
q = 5
