Question

A) Solve and check by substitution if your answer is correct.
1) 2x -9 = 11
2) 6(2 + a) = 3(8-a)
3) 4x-3=2x-1​

Answer 1

Answer:

1) x = 10

2) a = 4/3

3) x = 1

Step-by-step explanation:

1) 2(10) -9 = 11

20-9 = 11

2) 6(2+4/3) = 3(8-4/3)

6(6+4)/3 = 3(24-4)/3

20 = 20

3) 4(1)-3 = 2(1)-1

1=1
