I Like Math


I'm so bored, I'll even solve the math equations on these ads. In case anyone is interested, x = 49. I didn't even solve it properly, I just kept doing guess and check until I solved for it. 😒

LEGEND: sq(x) = square root of (x)
Now, the proper solution:

Rearrange:
sq(x+15) = 15 − sq(x)

Square both sides:
x + 15 = 225 − 30sq(x) + x

Subtract x from both sides:
15 = 225 − 30sq(x)

Add 30sq(x) to both sides:
30sq(x) + 15 = 225

Subtract 15 from both sides:
30sq(x) = 210

Divide 30 for both sides:
sq(x) = 7

Square both sides:
x=49 (SOLVED)
