Zero out the Y to find X
3X - 2(0) = -789
3X = -789
X = -263
-------------
now to check you need to find Y, so zero out X
3(0) - 2Y = -789
- 2Y = - 789
Y = 394.5 0r 394 and 1/2
convert to fraction
= 789/2
------------
check
3(-263) - 2(789/2) = -789
-789 - 2(789/2) = -789
cancel one 2 and multiply through by that 2
-1578 + 789 = - 789
-789 = - 789

What is 3x 2y?
3x times 2y = 3x2y In a system of equations, you can only solve for a system if there are the same amount of variables as equations. Since there is only one equation (actually, it is a monomial, but considering 3x2y=0) and there are two variables, x and y, we cannot solve for the variables. The simplest form is 3x2y.
How do you write 789 in expanded form?
