Answer:
−7/18
Step-by-step explanation:
Subtract 5/9 from both sides of the equation
Sure. We have
and
so the midpoint M is
![M = \frac 1 2(E+C) = ((2t+2p)/2, (0+2r)/2)=(t+p,r)](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%201%202%28E%2BC%29%20%3D%20%28%282t%2B2p%29%2F2%2C%20%280%2B2r%29%2F2%29%3D%28t%2Bp%2Cr%29)

Answer:
x = 22
Step-by-step explanation:
Step 1: Write equation
2(x + 9) = 4(x - 7) + 2
Step 2: Solve for <em>x</em>
- Distribute: 2x + 18 = 4x - 28 + 2
- Combine like terms: 2x + 18 = 4x - 26
- Subtract 2x on both sides: 18 = 2x - 26
- Add 26 to both sides: 44 = 2x
- Divide both sides by 2: 22 = x
- Rewrite: x = 22
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
2(22 + 9) = 4(22 - 7) + 2
2(31) = 4(15) + 2
62 = 60 + 2
62 = 62
