Which answer shows the correct steps to solve the equation
10+5x/15=4
a
Subtract 4 from both sides,, multiply by 12 on both sides, subtract 10 from both sides, and divide both sides by 5 to get x=2/5
b
Multiply by 15 on both sides, subtract by 10 on both sides, and divide by 5 on both sides to get x=10
c
Subtract 10 from both sides, multiply by 15 on both sides, and divide by 5 to get x=(-18)
d
Subtract 5x from both sides, subtract 10/15 from both sides, and divide both sides by 5 to get x=10
a) Subtract 4 from both sides, multiply by 15 on both sides, subtract 10 from both sides, and divide both sides by 5 to get x=2/5
The correct answer is option a: Subtract 4 from both sides, multiply by 12 on both sides, subtract 10 from both sides, and divide both sides by 5 to get x=2/5.
Here are the correct steps to solve the equation:
1. Subtract 4 from both sides:
10 + 5x/15 - 4 = 4 - 4
5x/15 + 6 = 0
2. Multiply both sides by 15 to eliminate the fraction:
(15)(5x/15 + 6) = (15)(0)
5x + 90 = 0
3. Subtract 90 from both sides:
5x + 90 - 90 = 0 - 90
5x = -90
4. Divide both sides by 5 to solve for x:
5x/5 = -90/5
x = -18/5 or x = 2/5
