Ответ:
First, subtract 9 from both sides. / Your problem should look like: 4(x - 1) = 25 - 9
Second, simplify 25 - 9 to get 16. / Your problem should look like: 4(x - 1) = 16
Third, divide both sides by 4. / Your problem should look like: x - 1 =
Fourth, simplify
Fifth, add 1 to both sides. / Your problem should look like: x = 4 + 1
Sixth, add 4 + 1 to get 5. / Your problem should look like: x = 5
x = 5

Simplify:
9+4(x−1)=25
9+(4)(x)+(4)(−1)=25(Distribute)
9+4x+−4=25
(4x)+(9+−4)=25(Combine Like Terms)
4x+5=25
Subtract 5 from both sides.
4x+5−5=25−5
4x=20
Divide both sides by 4.
4x/4=20/4
x=5
