–2x + 2y = 6
4x +2y=-5

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

-2x+2y=6,4x+2y=-5

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

-2x+2y=6

-2x=-2y+6

x=-\frac{1}{2}\left(-2y+6\right)

x=y-3

4\left(y-3\right)+2y=-5

4y-12+2y=-5

6y-12=-5

6y=7

y=\frac{7}{6}

Step-by-step explanation:

x=\frac{7}{6}-3

x=-\frac{11}{6}

x=-\frac{11}{6},y=\frac{7}{6} the answer

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
