Solve the linear system of equations using addition. graph the equations to verify your solution. -4x = y + 3 y= -4x - 3

Infinite solutions.

Step-by-step explanation:

-4x = y + 3(1)

y = -4x - 3(2)

Rearranging equation (1)

y = -4x - 3 (3)

Adding  (2) and (3) we get

0 = 0.

The original equations are identical and their graph will be the same straight line.

Any point on the line is a solution of this system, so there are infinite solution.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
