Answer: X= 15/4
Step-by-step explanation:
Subtract 2x from both sides
-x 2-2x=2x-15-2x
Simplify
-4x=-15
Divide both sides by -4
4x/-4 = -15/-4
Simplify
X=15/4

Answer:
Step-by-step explanation:
Sean buys some T-shirts for $12 each and the same number of belts for $7.50 each. Write an expression in the simplest form that represents the total amount.
So n represents the same number for t-shirts and belts.
Therefore n x 12.50 + n x 7.50 OR n(12.50+7.50)
The problem the student made was that they multiplied 12 times n plus 7.50. They forgot to multiply n times 7.50.
An expression that represents the total amount spent is 12n + 7.50n
Hope this helps!
X+2y=10
6x+6y=6 -> x+y=1
(x+2y=10)-(x+y=1)=y=9
x+(2*9)=10
x+18=10
x=-8 and y=9 -> c
Do you know whats the slope of the line on the graph ?
