Question

Find the value of x and show how

Answer 1

Answer:

The value of $x=11$

Step-by-step explanation:  Simplify the equation  $(4x+8) + (3x+7) = 92$  

To simplify take the common factors and solve them

So, 4x and 3x, then 8 and 7.  $4x + 3x = 7x \\8 + 7 = 15$

Now put 7x and 15 in the equation.   $7x + 15 = 92$

Now simply this equation.     7x + 15 = 92

                                                     - 15 = -15

cross out 7 to get x                7x         =  77    divide 77 and 7

                                                7               7    

                                                 x           = 11

To check work just replace the x with eleven to solve the equations and add the result to see if it equals 92

(4(11)+8) + (3(11)+7) = 92

(4 x 11 = 44 +8) = 52           52

+ (3 x 11 = 33 + 7) = 40     + 40

                                         = 92

So that means x is 11
