Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,<u>44</u>
Y can equal: 1.5,3,4.5,<u>6</u>,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.
Answer:Add 4.3x to both sides of the equation.
Step-by-step explanation:
The given equation is expressed as
3.7x - 18 = - 4.3x - 34
The main aim is to solve for x and x is on the left hand side and the right hand side of the equation. So the most efficient step would be to make all the terms containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation.
Therefore, the most efficient first step to solve for x in the equation would be
Add 4.3x to both sides of the equation.
Erin bought 8 pounds of apples, and Katie bought 5.
8-5=3
8+5=13
3.1415926535 is the ones I have memorized. Shouldnt need to know more then that
So first your going to multiply 2 times 3x= 6x
and multiply 2 by -3y= -6y
so now the equation is 4x+8y+6x-6y
then combine like terms
4x+6x
and 8y-6y
equals 10x+2y
