Question

An equation is shown below:

7(2x − 3) = 1

Which of the following correctly shows the first two steps to solve this equation?

Step 1: 9x − 7 = 1; Step 2: 9x = 8
Step 1: 9x + 4 = 1; Step 2: 9x = −3
Step 1: 14x − 3 = 1; Step 2: 14x = 4
Step 1: 14x − 21 = 1; Step 2: 14x = 22

Answer 1

it is d, step 1: 14x - 21; step 2: 14x=22

Explanation:

7(2x-3)=1 1. multiply 7 with (2x) and (-3)

14x-21=1 2. +21 on both sides

14x= 22 3. /14 on both sides

x=1.8

but I will say d is the correct answer
