Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
- 12 -12
2. 1/4(x) = -10 - 1/4 since its a fraction, you'll have to subtract not divide
-1/4 - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
Answer:
x=-3/11
Step-by-step explanation:
(x+3)/5 +2x=0
Multiply both sides by 5 to get rid of the fraction
5*( x+3)/5 +5*2x=0*5
x+3 + 10x =0
Combine like terms
11x +3 = 0
Subtract 3 from both sides
11x+3-3 =0-3
11x = -3
Divide by 11
11x/11 = -3/11
x = -3/11
