8/(2x -2) = 14/(3x)
Cross multiply
24x = 28x - 28
Simplify. Isolate the x
24x (-28x) = 28x (-28x) - 28
24x - 28x = -28
-4x = -28
-4x/-4 = -28/-4
x = 6

(x-10)/5 = 39/15
Cross multiply
15(x - 10) = 39(5)
Simplify
15x - 150 = 195
Isolate the x
15x - 150 (+150) = 195 (+150)
15x = 345
15x/15 = 345/15
x = 23
-----------------------------------------------------------------------------------------------------------------
(x + 4)/6 = (2x + 4)/9
Multiply 6 to both sides & 9 to both sides
9(x + 4) = 6(2x + 4)
Distribute 9 to x and 4, and 6 to 2x and 4
9x + 36 = 12x + 24
Isolate the x.
9x (-12x) + 36 (-36) = 12x (-12x) + 24 (-36)
9x - 12x = 24 - 36
-3x = -12
Isolate the x. divide -3 from both sides
-3x/-3 = -12/-3
x = -12/-3
x = 4

Answer:
50+30z=250+10z
z=10
Step-by-step explanation:
50+30z=250+10z
Substract 50 on both sides
50+30z-50=250+10z-50
Simplify
30z=10z+200
Substract 10z on both sides
30z-10z=10z+200-10z
20z=200
200/20 = 10
Answer z=10
Can someone please go over to my page and help me answer this question, its worth 99 points, no joke.
48x² + 8 = 8(6x² + 1) [we factor out 8, because 48 and 8 are divisible by 8]
