4y = x + 8
<u>x = 2/3y + 2</u>
4y = x + 8
<u>2/3y = x + 2</u>
<u>3 1/3y </u>= <u> 8 </u>
3 1/3 3 1/3
y = 2 2/5
4(2 2/5) = x + 8
9 3/5 = x + 8
<u> -8 -8</u>
1 3/5 = x
(x y) = (1 3/5, 3)

Step-by-step explanation:
<u>Step 1: Define Equation</u>
-(5 - 8x) + 4x = -89
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute negative: -5 + 8x + 4x = -89
- Combine like terms: -5 + 12x = -89
- Isolate <em>x</em> term: 12x = -84
- Isolate <em>x</em>: x = -7
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: -(5 - 8(-7)) + 4(-7) = -89
- Multiply: -(5 + 56) - 28 = -89
- Add: -61 - 28 = -89
- Subtract: -89 = -89
Here we see that -89 does indeed equal -89.
∴ x = -7 is the solution to the equation.
Its B
-130 + 240= 110
110- 56 = 54
So.. 54 is your answer
