Answer:
<h2><u>
X= 1</u></h2>
Step-by-step explanation:
<em>y = 5 - 3x</em>
<em>5x - 4y = -3</em>
you substitute for y since you know what y equals.
so, it will then be
5x -4(5 -3x) = -3
you then multiply -4 by everything in the parenthesis
so then it will be
5x - 20 + 12x = -3
Then combine like terms
5x + 12x = 17x
then the new equation is
17x -20 = -3
the next step is to and 20 to both sides since it is negative you do the opposite.
17x - 20 = -3
<u> + 20 +20</u>
17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.
<h2><u>
so, X = 1</u></h2>
Una década son 10 años
70 décadas entonces serán 700 años
12 meses en un año entonces será 700 x 12= 8400 meses
Step-by-step explanation:
x + 6 = 2x - 8
1. Subtract 2x from both sides
x - 2x + 6 = 2x - 2x - 8
2. Simplify
-x + 6 = -8
3. Now, subtract 6 from both sides
-x + 6 - 6 = -8 - 6
4. Simplify
-x = -14
5. Divide both sides by -1 because you would want the x by itself instead of having -x
-1x/-1 = -14/-1
6. Simplify
x = 14 <------ Answer
Hope that helped!!
