Have a nice day! :)
You would use PEMDAS
P stands for parentheses, x-5 can’t be simplified, so on to E.
E stands for exponent so next you would square x-5 getting x^2-10x+25.
M stands for multiplication, you multiply your result from E by -2. So, -2(x^2-10x+25)+8. And then -2x^2+20x-50+8.
D stands for division, and there is none so moving on.
A stands for addition, and so we add next. -2x^2+20x-42.
You can’t simplify any further so there you go!
Hope this helps!
<u>Answer:</u>
<u>Solution:</u>
-3x - 4y = -17
2(-3x - 4y = -17)
-6x - 8y = -34
- => -3y = -15
- => 3y = 15
- => y = 5
<u>Now, let's take one equation and substitute the value of y in it.</u>
- 6x + 5y = 19
- => 6x + 5(5) = 19
- => 6x + 25 = 19
- => 6x = 19 - 25
- => 6x = -6
- => x = -1
<u>Check:</u>
- => -3x - 4y = -17
- => -3(-1) - 4(5) = -17
- => 3 - 20 = -17
- => -17 = -17
<u>Hence, this is proven correct.</u>

Answer:
x=3.5
Step-by-step explanation:
1. Multiply
18x-12=5x+30
2. Move the x's to one side
12x= 42
3. Isolate the variable by dividing
x=3.5
