If 4x - 3 = 25 then x =

4x - 3 = 25

    + 3   + 3

4x = 28

x = 7

1st = add like terms

2nd = simplify

3rd = divide both sides

Hope this helps

x=7

Step-by-step explanation:

Step 1: Add 3 to both sides.

4x-3+3=25+3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

X=7

Hope this helps:)

< 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)
