Which step gives an incorrect property or reason in the process of solving the equation? -4(3x+6) +6=-30

-12x-12+6=-30 by the distributive property (Step 1)

-12x -6=-30 by the Commutative Property (Step 2)

-12x -6+6 = -30 +6 Addition (Step 3)

-12x +0 = -24 Additive inverse & Substitution (Step 4)

-12x = -24 Additive Identity (Step 5)

answer: the answer is ann

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
