There can be 1 or 2 but a total committee in total with boys and girls would be 4
Hey there!
k - 10/2 = -7
k - 5 = -7
ADD 5 to BOTH SIDES
k - 5 + 5 = -7 + 5
CANCEL out: -5 + 5 because that gives you 0
KEEP: -7 + 5 because it helps solve for the k-value
NEW EQUATION: k = -5 + 7
SIMPLIFY IT & YOU HAVE YOUR ANSWER!
k = -2
Therefore, your answer is: k = -2
Good luck on your assignment and enjoy your day!

Answer:
1) James brother is 10-x years old
2) James was 3 years ago x-3 years old
3) James brother was 3 years ago 7-x years old
4) 3(x-3)=7-x
5) James is 4 years old, his brother is 6 years old
Step-by-step explanation:
3) 10 - x - 3 = 7 - x
5) 3* James age 3 years ago = James brothers age 3 years ago
<=> 3*(x-3) = 7-x
<=> 3x - 9 = 7 - x
<=> 4x = 16
<=> x = 4
Just add the two numbers that make the big circle.
36 plus 26 which is 62
is that an awnser?
1) Equal the two together (not including the ‘y’)
-x -2 = 4x + 3
2) put x together and the whole number together
* when switching sides, signs ( + & -) changes, watch out for that *
-x - 4x = 3 + 2
-5x = 5 divide by the # with x so you have x
—— ——-
-5. -5
x = -1
therefore, x = -1
For y just plug x into either equation
I’ll use y = 4x + 3
y = 4(-1) + 3
y = -4 + 3
y = -1
therefore, y = -1
