Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
[tex]7(2x)-3=19x-1[/tex]
- The order of operations is:
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
- Knowing that there's a parenthesis in our equation, we should multiply what's within it by [tex]7[/tex]. (If there is no symbol between a parenthesis and another integer, you can assume you are multiplying them.)
[tex]14x-3=19x-1[/tex]
- Next step is moving every integer with a [tex]x[/tex] in it to one side, and every other number to the other side.
[tex]14x-3=19x-1[/tex]
[tex]14x-19x=-1+3[/tex]
- Simplify this equation. Comment on this if your confused on anything.
[tex]-5x=2[/tex]
- Divide by [tex]-5[/tex] so [tex]x[/tex] is isolated.
[tex]x=\frac{2}{-5}=-\frac{2}{5}[/tex]
