4x + 3y = 4
x - 2y = -10, so add 2y to both sides gives x=2y-10, replace this into first equation gives:
4(2y-10) + 3y = 4, expand that gives 8y-40+3y=4, add 40 to both sides, this gives:
8y + 3y =44, or 11y = 44 giving you y=4.
You have solved for y, now solve for x:
4x + 3y = 4, gives 4x +12 = 4, or 4x=-8 giving x=-2.
So x=-2 and y=4.
QED.
