Question

Q.6 Solve the equation: 5(x - 1)-2 (X +8) = 9​

Answer 1

Answer:

X=10

Step-by-step explanation:

$5(x - 1) - 2(x + 8) = 9 \\ 5x - 5 - 2x - 16 = 9 \\ 5x - 2x - 5 - 16 = 9 \\ 3x - 21 = 9 \\ 3x = 9 + 21 \\ \\ x = 30 \div 3 \\ x = 10$

Answer 2

Answer:

5(x−1)−2(x+8)=9

5x−5−2x−16=9

5x−2x−5−16=9

3x−21=9

3x=9+21

x=30÷3

x=10
