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 ...

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...
