Solving the simultaneous equations works out as x = -2 and y = -2
So the lines intersect at: (-2, -2)

What is the variable in 3x2y in algebra?
They are: x and y and the expression can be simplified to 6xy
Type this equation in standard form 3x2y 7?
Without an equality sign it is not an equation
What is the answer to x plus y to 3rd power plus x minus y to 3rd power?
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
What is the degree of the polynomial -2xy3 plus 3x2y?
I will assume that you mean -2xy3+3x2y. Then by "degree" is usually meant the total degree--the maximum sum of exponents of all variables. Here the first term has degree 1+3=4 and the second term has degree 2+1=3, so the degree of the entire expression is 4. It is also a 2nd degree expression in x and a 3rd degree expression in y.
Evaluate the expression 3x2y when x equals 3 and y equals 5?
(3 * 3)(2 * 5) (9)(10) 90
What is the variable in 3x2y in algebra?
They are: x and y and the expression can be simplified to 6xy
What is the GCF of 15x2y3 and -18x3yz?
3x2y
What does Xy3 3x2y - 7 equal?
12
Is 3x2y-57x a polynomial why or why not?
It is a polynomial in x and y.
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.
What is the greatest common factor of 15x2y3 and -18x3yz?
The GCF is 3x2y
Type this equation in standard form 3x2y 7?
Without an equality sign it is not an equation
What is the answer to x plus y to 3rd power plus x minus y to 3rd power?
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
Which expression is equivalent to 12x2y-6xy-x plus 2xy-9x2y plus 5x?
3x2y - 4xy + 4x
What is the slope and y intercept of 2y-6 equals 3x?
2y-6=3x2y-3x-6=0-3x-6=-2y3/2x+3=yy-inercept= 3slope= y(2)-y(1)/x(2)-x(1)= 6-3/2-0= 3/2
Distributive property with variables?
Say the Question is 3(2y+5) Multiply both terms in the brackets by 3 so (3x2y)+(3x5) = 6y+15
