What is the solution of x plus y equals -2 and 2x plus 3y equals -9?
CeliciaMaynor
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

What is the solution of 3x plus 2y equals 13 and 2x plus 3y equals 12?
x = 3 and y = 2
X - 3y equals -3 and -2x plus 6y equals 12 solution?
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
