Answer:
think its x=3 hope it helps
12.50+0.40e=14.75+0.25e
-12.50 -12.50 Subtract 12.50 to elimanate on the right side to isolate e
0.40e=2.25+0.25e left from subtracting 12/50
-0.25 -0.25e subtract 0.25e to put e on one side.
0.15e=2.25 left from subtracting 0.25 e
0.15e/0.15=2.25/0.15 divide to isolate e and to get you're answer
e=15
Hope it helps!
Answer:
x = 5
Step-by-step explanation:
Here we want to simplify and solve for x:
8x - 5(x - 1) = 20
8x - (5x - 5) = 20 (distribute the 5)
8x - 5x + 5 = 20 (subtract each of the terms / distribute the understood -1)
3x = 15 (combine like terms)
x = 5
check your answer by plugging x = 5 back into the equation:
8(5) - 5(5 - 1) = 20
40 - (5*4) = 20
40 - 20 = 20
20 = 20
