13m-22=9m-6
13m-9m-22=-6
4m-22=-6
4m=-6+22
4m=16
m=16/4
m=4
<em>Therefore, m is 4</em>
Answer:
x=6
Step-by-step explanation:
81^x=27^(x+2)
3^4x=3^3(x+2)
4x=3(x+2)
4x=3x+6
x=6
Answer:
b = 320
Step-by-step explanation:
a + b = 880
1 - 4/7 = 3/7 (restant A)
1 - 1/4 = 3/4 (restant B)
(3/7) . a = (3/4) . b
a = (7/4) . b
a + b = 880
(7/4) . b + b = 880
7b + 4b = 880 . 4
11 b = 880 . 4
b = 320
3x + 4y = -5
-3x -3x
4y= -3x -5
/4 /4
y= -3/4x-5/4
3x + 3y = -2
-3x -3x
3y = -3x-2
/3 /3
y= -1x-2/3
