Answer:
? = 10
Step-by-step explanation:
Let " ? " be x.
5 / x = x / 20
x * x = 5 * 20
x² = 100
[ 100 = 10 x 10 = 10² ]
x² = 10²
x = 10
<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>
