Step-by-step explanation:
a) 2a + 4 = 8 has a = 2 as a solution.
Step-by-step explanation:
a) 2a + 4 = 8
→ 2a = 8 - 4
→ a = 4/2
→ a = 2
.°. a = 2
b) (a+4) = 8
→ a = 8 - 4
→ a = 4
.°. a ≠ 2
c) 2a - 4 = 8
→ 2a = 8 + 4
→ a = 12/2
→ a = 6
.°. a ≠ 2
d) 2(a-4) = 8
→ 2a - 8 = 8
→ 2a = 8 + 8
→ a = 16/2
→ a = 8
.°. a ≠ 2
By seeing the solutions of the equations given, we get a) 2a + 4 = 8 has a = 2 as the Solution.
