In that case, x must be equal to zero. (0)
It is an equation of: 5x+3 = 28 and its solution is x = 5 5 times x plus 3 equals 28. Subtract 3 from both sides of the equation. 5 times x equals 25. Divide both sides of the equation by 5. x equals 5. (stop)
The equation 7 times 42 is equal to 294.
4x2 - x = 3
7 times 9 is 63.
You can't. For example if your equation is: 2x+7=12 then you will subtract 7 by itself, then subtract 7 from 12. You then get 2x=5. You will then divide 5 by 2 and you will get x=2.5 as your final answer.

One equation that could equal 141 is 70.5 times 2.
It means 0.07 times 16 = 1.12
It could be the area formula for a rectangle which is: area = length times width
you need to equal them out, so it is actually 48 over 56 (times by 8) subtract 7 over 56 (times by 7). so the answer is 41 over 56.
This can be answered in two ways... If you're talking about Einstein's equation, then E=MC2. If you are wondering what E means, it stands for energy, so Einstein's equation means, "energy is equal to mass times the speed of light squared'.
