Solve the equation 5(x-2)=7(x+4) for x

Sphinxa [80]

Answer:

$\boxed{\bold{x=-19}}$

Step By Step Explanation:

Expand $\bold{5\left(x-2\right): \ 5x-10}$

Expand $\bold{7\left(x+4\right): \ 7x+28}$

$\bold{5x-10=7x+28}$

Add 10 To Both Sides

$\bold{5x=7x+38}$

Subtract 7x From Both Sides

$\bold{5x-7x=7x+38-7x}$

Simplify

$\bold{-2x=38}$

Divide Both Sides By -2

$\bold{\frac{-2x}{-2}=\frac{38}{-2}}$

Simplify

$\bold{x=-19}$

Arturiano [62]

Answer:

There are 18 girls in a group that has 16 boys.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Number of girls in the grade = 81

Number of the boys in the grade = 72

Number of students in the grade = 81 + 72 = 153

2. Let's find the number of girls in a group that has 16 boys.

For getting that number we will use the Rule of three simple, this way:

Number of girls in a group that has 16 boys = (81 * 16)/72

Number of girls in a group that has 16 boys = 1,296 / 72

Number of girls in a group that has 16 boys = 18

There are 18 girls in a group that has 16 boys.
