The x (the second one) has a one in front of it so 5x *1x=5x so 5x-4 is the answer
Answer:
6.00 %
Step-by-step explanation:
205.00 × 0.060= 12.3
205.00 + 12.3= $217.30
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6
6 ( 31/6 - 4) = 7
186/6 - 24 = 7
186/6 = 144/6 = 7
42/6 = 7
7 = 7
the answer to the question is 2.6
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.
