Step-by-step explanation:
x+x+7=103
-7 -7
2x=96
/2 /2
x=48
Mikhail is 48
Answer: -46
Step-by-step explanation:

(y - 5)/3 = 1
y - 5 = 3 x 1 = 3
y = 3 + 5 = 8
6x + 29 = 5
6x = 5 - 29 = -24
x = -24/6 = -4
Here are some examples of how the Quadratic Formula works:
<span>Solve <span>x2 + 3x – 4 = 0</span></span>
This quadratic happens to factor:
x2 + 3x – 4 = (x + 4)(x – 1) = 0
.
Then, as expected, the solution is <span>x = –4, x = 1</span>.
