Answer:
x = 3
Step-by-step explanation:
8x -6 = 18
Add 6 to both sides.
8x = 24
Divide both sides by 8 to isolate x.
x = 3
2w + 8 = 13
Subtract 8 from both sides.
2w = 5
Divide both sides by 2.
w = 5/2
<span>4x^2 - 25
= (2x)^2 - 5^2 .................using a^2 - b^2 = (a+b)(a-b)
= (2x + 5)(2x - 5)</span>
