Answer:
26, 37
Step-by-step explanation:
1+1 = 2
2+3=5
5+5=10
10+7=17
17+9=26
26+11-37

Step-by-step explanation:
<u>Step 1: Define</u>
10 + 4a = a - 23
<u>Step 2: Solve for </u><em><u>a</u></em>
- Subtract <em>a</em> on both sides: 10 + 3a = -23
- Isolate <em>a </em>term: 3a = -33
- Isolate <em>a</em>: a = -11
<u>Step 3: Check</u>
<em>Plug in a into the original equation to verify it's a solution.</em>
- Substitute in <em>a</em>: 10 + 4(-11) = -11 - 23
- Multiply: 10 - 44 = -11 - 23
- Subtract: -34 = -34
Here we see that -34 does indeed equal -34.
∴ a = -11 is the solution to the equation.
Answer:
x = 18.
Step-by-step explanation:
x / 1.2 = 15
To isolate x we multiply both sides of ther equation by 1.2:
x = 15 * 1.2
x = 18 (answer).
F (x)=(x+4)/6
f-1 (7)=x
f (f-1 (7)=f (x)
7=f (X)
7=(x+4)/6
x+4=42
x=38
