Answer:
Step-by-step explanation:
4b + 8 = 20
Subtract 8 from both sides
4b + 8 - 8 = 20 - 8
4b = 12
Now divide both sides by 4
4b/4 = 12/4
b = 3
Check:
LHS = 4b + 8
= 4*3 + 8
= 12 + 8
= 20 = RHS

Answer:
x = 3
Step-by-step explanation:
A parallelogram must have two pairs of parallel sides.
For this to be true, the alternate exterior angles of the diagonal must be congruent.
Hence the equation,
<u>10x + 4 = 13x - 5</u>
Simplify.
<u>9 = 3x</u>
<u>x = 3</u>
