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...

3 (y + 4) - 2 (4y + 1)= 3y + 12 - 8y - 2= (3y - 8y) + (12 - 2)= 10 - 5y

This answer would be best shown using a diagram. However you must ensure that the graph crosses the x axis at -180, 0 and 180 degrees. Moreover it is also necessary that the student has included asymptote...
