5x + 15 = 28x
Subtract 5x from each side:
15 = 23x
Divide each side by 23:
15/23 = x
That's about 0.652 (rounded).
2x57-99 equal 15
x = -11
minus 15.
That depends on what the value of x is.
It equals 285
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
2x57-99 equal 15
it can't equal 550....i think it equals 15
If 40 plus x equals 25 then x is equal to -15.
Yes that is correct
46 + 15 + 85 = 146
x = -11
minus 15.
That depends on what the value of x is.
15+7=22
It equals 285
5 + -8 = 3 + 12 -3 is not equal to 15
