Answer:
11) x = -5
12) x = -12
13) x = 6
14) y = -9
15) No solution
16) Infinite Solutions
Step-by-step explanation:
11)_______________
5x + 10 = 3x
-5x -5x
10 = -2x
divide by -2
x = -5
12)_______________
6p + 4 = 5p - 8
+8 +8
6p + 12 = 5p
-6p -6p
12 = -1x
x = -12
13________________
3x - 22 = -8x + 44
+22 +22
3x = -8x + 66
+8x +8x
11x = 66
x = 6
14________________
-11(k + 4) = 55
-11y - 44 = 55
+44 +44
-11y = 99
y = -9
15________________
6(c - 8) = 5(2c - 12) - 4c
6c - 48 = 10c - 60 - 4c
6c - 48 = 6c - 60
+48 +48
6c = 6c - 12
-6c -6c
No Solution
16________________
-12y + 21 = -3(5y - 7) + 3y
-12y + 21 = -15y + 21 + 3y
-12y + 21 = -12y + 21
both sides are the same, so
Infinite Solutions
