Answer:
25 and 100
Step-by-step explanation:
<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>
Yes, 5:4 is the simplified form of 25:16. 25 divided by 5 is 5 (the lowest possible number it can be made into). 16 divided by 4 is 4 (also the lowest possible number it can be made into).
X = 2
So 6 + 2 = 8
6 - 2 = 4
8 x 4 = 32
(6-x)(6+x) = 32
36 - x^2 = 32
-36. -36
-x^2 = -4
X = 2
