Answer:
x = 3
Step-by-step explanation:
<u>Step 1: Plug in 12 for y</u>
<em>2x - 18 = -2(12) + 12</em>
<em />
<u>Step 2: Multiply</u>
<em>2x - 18 = -24 + 12</em>
<em />
<u>Step 3: Combine</u>
<em>2x - 18 = -12</em>
<em />
<u>Step 4: Add 18 to both sides</u>
2x - 18 + 18 = -12 + 18
<em>2x = 6</em>
<em />
<u>Step 5: Divide both sides by 2</u>
2x / 2 = 6 / 2
<em>x = 3</em>
<em />
Answer: x = 3
Answer:
3
Step-by-step explanation:
2x - 18 = -2y + 12
If y = 12
Therefore,
2x - 18 = -2 x 12 + 12
2x - 18 = -24 + 12
2x - 18 = -12
Add 18 to both sides
2x - 18 + 18 = -12 + 18
2x = 6
Divide both sides by 3
2x/2 = 6/2
x = 3
