Multiply one equation to make the number of $$x$$'s or $$y$$'s the same. Then add or subtract the equations to eliminate either $$x$$ or $$y$$. Solve the following equations:

### Question 2

 (a) $$2x + y = 11$$ (b) $$6x + 5y = 8$$ (c) $$3x + 2y = 8$$ (d) $$4x - 3y = 15$$ $$4x + 8y = 52$$ $$3x + 3y = 6$$ $$6x + 5y = 17$$ $$2x - 6y = 12$$ (e) $$12x - 3y = -6$$ (f) $$6x + 2y = 3$$ (g) $$4x + 5y = 12$$ (h) $$2x + 5y = 11$$ $$4y - 4x = 11$$ $$10x - 10y = -3$$ $$2x - 6y = 40$$ $$4y - 2x = 7$$ (i) $$8x + 4y = -2$$ (j) $$x + 7y = 33$$ (k) $$10x + 6y = -22$$ (l) $$3x - 4y = 1$$ $$4x - 2y = 7$$ $$2x - 3y = -19$$ $$5x - 3y = 19$$ $$4x + 8y = -4$$
