what is the value of 11x - 2 when 7x + 3 = 17?
7 times 2=14 +3=17
11 times 2=22 -2=20
To find the value of 11x - 2 when 7x + 3 = 17, we need to solve the equation 7x + 3 = 17 first.
Step 1: Subtract 3 from both sides of the equation:
7x + 3 - 3 = 17 - 3
Simplifying, we get:
7x = 14
Step 2: Divide both sides of the equation by 7:
7x/7 = 14/7
Simplifying further gives us:
x = 2
Now that we have the value of x, we can substitute it back into the expression 11x - 2 to find the final result.
Substituting x = 2:
11(2) - 2
= 22 - 2
= 20
Therefore, the value of 11x - 2 when 7x + 3 = 17 is 20.
