User: If we read the reaction as X + Y ? Z + Q it is

Weegy: Simplifying (x * y) + (x * z) + (y * z) = t Multiply x * y (xy) + (x * z) + (y * z) = t xy + (x * z) + (y * z) = t Multiply x * z xy + (xz) + (y * z) = t xy + xz + (y * z) = t Multiply y * z xy + xz + (yz) = t xy + xz + yz = [ t Solving xy + xz + yz = t Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1yz' to each side of the equation. xy + xz + yz + -1yz = t + -1yz Combine like terms: yz + -1yz = 0 xy + xz + 0 = t + -1yz xy + xz = t + -1yz Reorder the terms: -1t + xy + xz + yz = t + -1yz + -1t + yz Reorder the terms: -1t + xy + xz + yz = t + -1t + -1yz + yz Combine like terms: t + -1t = 0 -1t + xy + xz + yz = 0 + -1yz + yz -1t + xy + xz + yz = -1yz + yz Combine like terms: -1yz + yz = 0 -1t + xy + xz + yz = 0 ]
