First, we gather like terms: 7x + 5x = -42 - 6 This gives: 12x = -48Now we can divide both sides by 12 to solve for x: 12x/12 = -48/12This gives: x = -4

To solve simultaneous equations we need to make either the y coefficients or the x coefficients equal so that we can cancel them out. For this set of equations we are going to make the x coefficients the ...

e^ln(2x-3) = e¹
2x-3 = e
x = (e+3)/2

Assuming knowledge of solving regular quadratic equations.Treat this as a regular quadratic equation, except it is in terms of sin(x) instead of just x as you might be used to.So using the quadratic equat...

Under 0 degree celcius, ice crystals will begin to form in the cell membrane of the enzyme. If the temperature increases and the enzyme thaws, the pierced cell membrane will cause leakage and prevent the ...
