You are given two equations, solve for one variable in one of the equations. Say you solved for x in the second equation. Then, plug in that value of x in the x of the first equation. Solve this (first) equation for y (as it should become apparent) and you'll get a number value. Plug in this numerical value of y into the y of the second equation. Solve for x in the second equation. And there you have it: (x, y)

(x+2)(4+y)(5+6)(2+x)(4+0.5x)

Yuki888 [10]

(x+2)(4+y)(5+6)(2+x)(4+0.5x)

combine like terms

(x+2) (4+y) (11) (x+2) (4+.5x)

11(x+2)^2 (4+y)(4+.5x)

distribute

11(x^2 +4x+2) (16+4y+2x+.5xy)

(11x^2+44x+22)(16+4y+2x+.5xy)

5.5 x^3 y + 22 x^3 + 66 x^2 y + 264 x^2 + 198 x y + 792 x + 176 y + 704
