solving equations with variables on both sides.
you dont have to answer all questions
but who ever gives me all the answers FIRST ill choose you for best answer!
11(p-3)=5(p+3)
9(m+2)=-6(m+7)
2(x+7)=5(x-7)
5x + 7 = 6x
Can you please answer my math questions its easy!?

11(p - 3) = 5(p + 3)
11p - 33 = 5p + 15
6p = 48
p = 8
9(m + 2) = - 6(m + 7)
9m + 18 = - 6m - 42
15m = - 60
m = - 4
2(x + 7) = 5(x - 7)
2x + 14 = 5x - 35
3x = 48
x = 16
5x + 7 = 6x

1)
11(p - 3) = 5(p + 3)
11*p - 11*3 = 5*p + 5*3
11p - 33 = 5p + 15
11p - 5p = 33 + 15
6p = 48
p = 48/6
p = 8
2)
9(m + 2) = -6(m + 7)
9*m + 9*2 = -6*m - 6*7
9m + 18 = -6m - 42
9m + 6m = -18 - 42
15m = -60
m = -60/15
m = -4
3)
2(x + 7) = 5(x - 7)
2*x + 2*7 = 5*x - 5*7
2x + 14 = 5x - 35
2x - 5x = -14 - 35
-3x = -49
x = -49/-3
x = 49/3
4)
5x + 7 = 6x
5x - 6x = -7
x = -7/-1
x = 7
11(p - 3) = 5(p + 3)
11*p - 11*3 = 5*p + 5*3
11p - 33 = 5p + 15
11p - 5p = 33 + 15
6p = 48
p = 48/6
p = 8
2)
9(m + 2) = -6(m + 7)
9*m + 9*2 = -6*m - 6*7
9m + 18 = -6m - 42
9m + 6m = -18 - 42
15m = -60
m = -60/15
m = -4
3)
2(x + 7) = 5(x - 7)
2*x + 2*7 = 5*x - 5*7
2x + 14 = 5x - 35
2x - 5x = -14 - 35
-3x = -49
x = -49/-3
x = 49/3
4)
5x + 7 = 6x
5x - 6x = -7
x = -7/-1
x = 7

11(p-3) = 5(p+3)
11p-33 = 5p+15
11p-5p = 15+33 (transferring p terms to left side, and numbers to right
side)
6p = 48
so, p = 48/6
value of p = 8
9(m+2) = 6(m+7)
9m+18 = 6m+42
9m-6m = 42-18
3m = 24
so, m = 8
2(x+7) = 5(x-7)
2x+14 = 5x-35
5x-2x = 14+35
3x = 49
so x = 49/3 = 16.33
5x+7 = 6x
5x - 6x = -7
-x = -7,
so x=7
11p-33 = 5p+15
11p-5p = 15+33 (transferring p terms to left side, and numbers to right

6p = 48
so, p = 48/6
value of p = 8
9(m+2) = 6(m+7)
9m+18 = 6m+42
9m-6m = 42-18
3m = 24

2(x+7) = 5(x-7)
2x+14 = 5x-35
5x-2x = 14+35
3x = 49
so x = 49/3 = 16.33
5x+7 = 6x
5x - 6x = -7
-x = -7,
so x=7

11(p-3)=5(p+3), So 11p -33 =5p+15, 11p-5p=15+33,6p=48,p=8
9(m+2)=-6(m+7), So 9m+18= -6m - 42, 9m+6m =-60 so m = - 4
2(x+7)=5(x-7) here 3x = 49 so x = 49/3
5x + 7 = 6x, so x = -7.
9(m+2)=-6(m+7), So 9m+18= -6m - 42, 9m+6m =-60 so m = - 4
2(x+7)=5(x-7) here 3x = 49 so x = 49/3
5x + 7 = 6x, so x = -7.
