Step-by-step explanation:
<u>Step 1: Define Equation</u>
2t + 5 = 2t + 5
<u>Step 2: Solve for </u><em><u>t</u></em>
- Subtract 5 on both sides: 2t = 2t
- Divide 2 on both sides: t = t
Here we see that <em>t</em> does indeed equal <em>t</em>.
∴ t = infinite amount of solutions

Answer:
x = 23 ; y = 15
Step-by-step explanation:
Given :
Let the numbers be : x and y
x + y = 38 - - (1)
x = y + 8 - - - (1)
Put x = y + 8 into (1)
y + 8 + y = 38
2y + 8 = 38
2y = 38 - 8
2y = 30
y = 30/2
y = 15
x = y + 8
x = 15 + 8
x = 23
