Step-by-step explanation:
<u>Step 1: Define Equation</u>
8(2x + 5) = 16x + 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 8: 16x + 40 = 16x + 40
- Subtract 40 on both sides: 16x = 16x
- Divide 16 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ <em>x</em> has an infinite amount of solutions.
<h3>Substitute and Check:</h3>
<h3>We can stop here and conclude that ( 1 , 3 ) is not a solution to this system, since it does not even satisfy the first equation, but check for the other one just in case:</h3>
Answer:
Step-by-step explanation:
4x + 15 = 3
Subtract 15 from both sides
4x + 15 - 15 = 3 - 15
4x = -12
Divide both sides by 4
4x/4 = -12/4
x = -3
Check:
substitute x = -3 in the LHS of the equation,
4*(-3) + 15 = -12 + 15
= 3 = RHS
