2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
(-1,-2)
x = 8, y = -1
x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5
It is -9
