Question

Find the value of x and show how

Answer 1

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
