Could you specify a bit more? Cause you might be referring to adjacent, congurent, and or vertical.
<h3><u>The value of a is equal to 0.93.</u></h3>
-6(7a - 4) = 3(a - 7) + 3
Distributive property.
-42a + 24 = 3a - 21 + 3
Add 42a to both sides.
24 = 45a - 21 + 3
Combine like terms.
24 = 45a - 18
Add 18 to both sides.
42 = 45a
a = 0.93
