Answer:
2.15 or 43/20.
Step-by-step explanation:
4x + 2/5 = 9
Transposing 2/5 to RHS and changing sign
⇒4x = 9 - 2/5
⇒ 4x = 9 - 0.4
⇒ 4x = 8.6
⇒ x = 8.6/4
⇒ x = 2.15 or 43/20.
Verification
Substitute x = 2.15 in the LHS, we get
4(2.15) + 2/5
= 8.6 + 2/5
= 8.6 + 0.4
= 9.
On RHS, we have
= 9
9 = 9
LHS = RHS
Hence, verified.
Our answer is correct!
