The answer is 10
Explanation: First you cross-multiply to get 2x=20 and then divide by 2 to get x=10
2x+4-3x=0
-4 -4
2x-3x=-4
-1x=-4
_ _
-1 -1
x=4
so the answer is x=4
Answer:
x = 8/3
Step-by-step explanation:
Solve for x:
6 x + 8 (5 - 7) = 0
5 - 7 = -2:
6 x + -2 8 = 0
8 (-2) = -16:
6 x + -16 = 0
Add 16 to both sides:
6 x + (16 - 16) = 16
16 - 16 = 0:
6 x = 16
Divide both sides of 6 x = 16 by 6:
(6 x)/6 = 16/6
6/6 = 1:
x = 16/6
The gcd of 16 and 6 is 2, so 16/6 = (2×8)/(2×3) = 2/2×8/3 = 8/3:
Answer: x = 8/3
