P=2(L+W)and P=146, W=4x+3, and L=3x so

146=2(4x+3+3x)

73=7x+3

70=7x

x=10

W=4x+3=43

L=3x=30

One less than four times a number is 11.

finlep [7]

X=the number
4x-1=11
If you wanted to solve it
4x-1=11
4x-1+1=11+1 add 1 on both sides
4x/4=12/4 divide 4 on both sides
x=3 solution

What is the value of x ? 6.75 + 3/8x = 13 1/4

Bad White [126]

Let's solve your equation step-by-step.

6.75+38x=1314

Step 1: Simplify both sides of the equation.

38x+6.75=534

Step 2: Subtract 6.75 from both sides.

38x+6.75−6.75=534−6.75

38x=132

Step 3: Multiply both sides by 8/3.

(83)*(38x)=(83)*(132)

x=523

it should now look like this:

2*9*5

3. Multiply left to right

2*9= 18
