Julie has three boxes of pens. The diagram shows expressions for the number of pens in each box. Look at these equations. Equals B +12
B equals C +4
Write an equation to show the relationship between a + c

a = c + 16

Step-by-step explanation:

a = b + 12

b = c + 4

Solve for b in the first equation.

a = b + 12

a - 12 = b

Put b as a - 12 in the second equation and solve for a.

a - 12 = c + 4

a = c + 4 + 12

a = c + 16

here,

a=b+12

b=a-12> equation (i)

b= c+4

putting the value of b from the equation (I)

a-12=c+4

a=c+4+12

a=c+16

hope this helps...

Good luck on your assignment...

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
