Question

60. Solve for x:
7x + 3 - 2(2x + 1) = 13

Answer 1

Explanation:

7x+3-2(2x+1)+13

• First, you need to distribute the numbers.

7x+3-4x+2=13

-2 -2

• Subtract the 2 from 3 to cancel the 2 out.

7x+1-4x=13

• subtract the 4x from 7x to cancel the 4x out.

3x+1=13

-1 -1

3x=12

• Divide 3x and 12 by 3.

x = 4

Answer 2

x=4

Explanation:

7x+3-2(2x+1)=13

7x+3-4x-2=13(collect like terms)

7x-4x+3-2=13

3x+1=13

3x=13-1

3x=12

divide both sides by 3

3x/3=12/3

x=4
