7 - 2x = 2(x - 4) - 1 solve

x = 4

Step-by-step explanation:

expand out the brackets to get   7 - 2x = 2x - 8 - 1

we can then add 2x to both sides to get        7  = 4x - 8 - 1

add 9 to both sides to get       16 = 4x

divide both sides by 4 to get     x = 4

hope that helps

Step-by-step explanation:

Here you go mate

→Use PEMDAS

Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction

→Step 1

7-2x=2(x-4)-1  Equation/Question

→Step 2

7-2x=2(x-4)-1  Remove parenthesis

7-2x=2x-9

→Step 3

7-2x=2x-9  Subtract 7

-2x=2x-16

→Step 4

-2x=2x-16  Simplify

-4x=-16

→Step 5

-4x=-16  Divide sides by -4

4

→Answer

∴your answer is x=4

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
