• Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

15s + t = 5

4s = 3t + 34

Step 2: Rewrite

15s + t = 5

1. Subtract t on both sides:                    15s = -t + 5
2. Multiply both sides by 3:                    45s = -3t + 15

Step 3: Redefine Systems

45s = -3t + 15

4s = 3t + 34

Step 4: Solve for s

Elimination

1. Combine equations:                    49s = 49
2. Divide 49 on both sides:             s = 1

Step 5: Solve for t

1. Define equation:                     15s + t = 5
2. Substitute in s:                         15(1) + t = 5
3. Multiply:                                   15 + t = 5
4. Isolate t:                                   t = -10

Answer 2

Answer:

Explanation is below

Step-by-step explanation:

Here ya go

Step 1

15s+t=5,4s=3t+34  Question

Step 2

4s=3t+34  Substitute  -15s+5

4s=3(-15s+5)+34

s=1

Step 3

t=-15s+5  Substitute 1 for s

t=(-15)(1)+5

t=-10

answer

s=1

t=-10
