Answer:
x= 2
Step-by-step explanation:
so you add the values given in the brackets and leave X as it is (do this on both sides of the equation.
1. (x + 5)(x+4)= (x+12)(x+1)
2. multiply the parenthesis on both sides or one at a time
so, [tex]x^{2}[/tex]+5x+4x+20 = [tex]x^{2}[/tex]+12+1x+12
3. cancel like terms which we have [tex]x^{2}[/tex] so remove that.
5x+4x+20=12+1x+12
4. collect like terms.
9x + 20 = 13x + 12
5. move like terms.
9x-13x=12-20 = -4 = -8
6. x= [tex]\frac{-4}{-8}[/tex] divide both sides by 4 or basically simplify 4 divided by 8
which leaves u with
x= 2
hope this helps x, let me know if u have any questions. photomath is an app that helps too.
