Answer:
M=-8
Step-by-step explanation:
21+6m=3(m−1)
Step 1: Simplify both sides of the equation.
21+6m=3(m−1)
21+6m=(3)(m)+(3)(−1)(Distribute)
21+6m=3m+−3
6m+21=3m−3
Step 2: Subtract 3m from both sides.
6m+21−3m=3m−3−3m
3m+21=−3
Step 3: Subtract 21 from both sides.
3m+21−21=−3−21
3m=−24
Step 4: Divide both sides by 3.
3m/3=-24/3
M=-8
12) -5k - 19 = 5 - 13k
-5k = 24 - 13k
8k = 24
k = 3
14) -15n + 16 = 86 - 29n
-15n = 70 - 29n
14n = 70
n = 5
16) 13 - 3p = -5(3 + 2p)
13 - 3p = -15 - 10p
-3p = -28 - 10p
7p = -28
p = -4
18) 14a - 93 = 49 - 57a
14a = 142 - 57a
71a = 142
a = 2
20) 8v = 2(4v + 2)
8v = 8v + 4
No solution
22) 2(-4h - 13) = 37 + 13h
-8h - 26 = 37 + 13h
-8h = 63 + 13h
-21h = 63
h = -3
24) 11n - 3 = 9 + 5n
6n = 12
n = 2
26) -9n - 12 = 8 - 4n
-5n - 12 = 8
-5n = 20
n = -4
Answer:
Place the f(x) expression 2x-3 into the x in the g(x) expression 4x+5, so it will be 4(2x-3)+5; you can expand it out if you want
