x-10/4 + 2/5 = - x/3
Re-writing:
x-%2810%2F4%29%2B%282%2F5%29=%28-x%2F3%29
Arranging similar terms:
x%2B%28x%2F3%29=%2810%2F4%29-%282%2F5%29
%283x%2Bx%29%2F3=%2850-8%29%2F20
4x%2F3=42%2F20, cross multiply
4x=126%2F20 ---> cross%284%29%2Ax%2Fcross%284%29=126%2F%284%2A20%29
x=%28126%2F80%29 divide both numerator & denominator by 2:
x=63%2F40
