Arrange the steps in the correct order to perform this subtraction problem. 1.1 × 103 – 4.9 × 102

1=1.1 x 10^3 - 4.9 x 10^2

2=1.1 x 10^3 -10/10 x 4.9 x 10^2

3=1.1 x 10^3 -0.49 x 10^3

4= (1.1 -0.49) x 10^3

5=0.61 x 10^3

6=10/10 x 0.61 x 10^3

7= 6.1 x 10^2

Step-by-step explanation:

i got it right

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
