Answer: x-2
Step-by-step explanation:
Without LCD :
1/2(4x + 6) = 1/3(9x - 24)
2x + 3 = 3x - 8
2x - 3x = -8 - 3
-x = - 11
x = 11
with LCD :
1/2(4x + 6) = 1/3(9x - 24) ...multiply by 6
3(4x + 6) = 2(9x - 24)
12x + 18 = 18x - 48
12x - 18x = -48 - 18
-6x = - 66
x = -66/-6
x = 11

Mixed number is a whole number and a fraction in the same number such as
2 2/3
Answer:
A) T = -1.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10t+4−2t=2−2(t+4)
10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)
10t+4+−2t=2+−2t+−8
(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)
8t+4=−2t+−6
8t+4=−2t−6
Step 2: Add 2t to both sides.
8t+4+2t=−2t−6+2t
10t+4=−6
Step 3: Subtract 4 from both sides.
10t+4−4=−6−4
10t=−10
Step 4: Divide both sides by 10.
Hope this helps!
