Answer:
x = -2
Step-by-step explanation:
Step 1: Write equation
5(x + 6) + 11 = 25 - 3x
Step 2: Solve for <em>x</em>
- Distribute 5 on both sides: 5x + 30 + 11 = 25 - 3x
- Combine like terms: 5x + 41 = 25 - 3x
- Add 3x to both sides: 8x + 41 = 25
- Subtract 41 on both sides: 8x = -16
- Divide both sides by 8: x = -2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(-2 + 6) + 11 = 25 - 3(-2)
5(4) + 11 = 25 + 6
20 + 11 = 25 + 6
31 = 31

Step-by-step explanation:
a + b = 7 ....eq 1
a - b = 3 ....eq 2
solve simultaneously using elimination method
add eq 2 to eq 1
a + b = 7
+
a - b = 3
2a = 10
a = 5
substitute the value of a in eq 1
5 + b = 7
subtract 5 from both sides
5 - 5 + b = 7- 5
b = 2
Now, slot in the values of both a and b
3^a÷3^b
we will solve using PEDMAS
3^5 / 3^2

Answer:
{4, 20}
Step-by-step explanation:
x2 − 24x = −80
divide -24 by 2 and square result get 144
x^2 - 24x + 144 = -80 + 144
(x - 12)^2 = 64
x - 12 = root (64)
x = 12 + 8 or x = 12 - 8
x = 20 or 4
