Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4x + y = 2

y = x - 3

Step 2: Solve for x

Substitution

Substitute in y:                    4x + (x - 3) = 2Combine like terms:           5x - 3 = 2Isolate x term:                     5x = 5Isolate x:                              x = 1

Step 3: Solve for y

Define equation:                    y = x - 3Substitute in x:                       y = 1 - 3Subtract:                                 y = -2

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
