What is... X/2 - 13 = 1

kow [346]

X ÷ 2 - 13 = 1
Write the division as a fraction
$\frac{1}{2}x - 13 = 1$
Multiple both sides of the equation by 2
$2 \times \frac{1}{2}x \times - 2 \times 13 = 12$
Reduce the number with greatest common divisor 2
$x - 2 \times 3 = 2$
Multiply the numbers
$- 2 \times 13$
Then u will have
$x - 26 = 2$
Move constant to the right by adding its opposite sides
$x - 26 + 26 = 2 + 26$
Eliminate the opposites
$- 26 + 26$
Then you have
$x = 2 + 26$
Add the numbers
$x = 28$

The number of girls in the Middle School Cyber Club was 6 more than double the number of boys, and in total there were 48 middle

Wittaler [7]

Answer:

g = number of girls;

b= number of boys

we know that: g= 6+2b

and that: g+b= 156 kids in total

so we may write g+b=(6+2b)+b=6+3b

but g+b= 156

so 6+3b = 156 => 3b= 156-6=150 => b=150/3=50 => b = 50 (number of boys)

g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)
