Is it an S or is it supposed to be a 5 if S I think it's written like 8.5s? or something like that? Sorry not too good at this.
Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for <em>e</em>
- Distribute -2: -16 + 2e = 2 - e
- Add e to both sides: -16 + 3e = 2
- Add 16 to both sides: 3e = 18
- Divide both sides by 3: e = 6
Step 3: Check
<em>Plug in e to verify it's a solution.</em>
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
Answer:
52 x 7= 50 x 7 + 2 x 7
Step-by-step explanation:
Answer:
1) x²-3x+9/4 = 81/4
2) x = 6, -3
Step-by-step explanation:
x²-3x-18=0
x²-3x=18
(b/2)² = (-3/2)² = 9/4; completing the square
x²-3x+9/4 = 18+9/4
(x-3/2)(x-3/2) = 81/4
x - 3/2 = ± 9/2
x = 3/2 ± 9/2
x = 6, -3
