Angle 3 = angle 7 [alternate angles]
=> 4x+1 = 2x + 21
=> 4x-2x = 21-1
=> 2x = 20
=> x = 20/2
=> x = 10
Answer:
Yes, the expressions are equivalent.
Step-by-step explanation:
Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.
and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.
Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2
