The number of girls in cobbs class is 2 less than 3 times the number of boys. She has 26 students in her class how many are boys

Natalka [10]

Answer:

7 are boys

Step-by-step explanation:

Make a system of equations where g is for girls and b is for boys.

b+g=26

g=3b-2

Substitute "3b-2" in for "g" in the first equation.

b+(3b-2)=26

Rewrite without the parentheses because it's addition and not multiplication.

b+3b-2=26

Combine like terms.

4b-2=26

Add 2 to both sides.

4b=28

Divide by the coefficient of the variable to get it alone.

b=7

Solve for x and y<br> 7x - 3y =23<br>2x - 4y = -8<br>

dybincka [34]

$Q. 7x - 3y =23$

$Lets, \: Find \: x :-$

$7x - 3y = 23$

$7x - 3(0) = 23$

$x = 3.286$

$Now, Lets \: find \: y :-$

$7x - 3y = 23$

$7(0) - 3y = 23$

$y \: = -7.667$
