Answer:
Step-by-step explanation:
18.4 + 8w = 6(-4.6 + 9w)
18.4 + 8w = (-4.6 * 6 + 9w * 6)
18.4 + 8w = (-27.6 + 54w)
18.4 + 8w + -54w = -27.6 + 54w + -54w
18.4 + -46w = -27.6 + 54w + -54w
18.4 + -18.4 + -46w = -27.6 + -18.4
Combine like terms: 18.4 + -18.4 = 0.0
0.0 + -46w = -27.6 + -18.4
-46w = -27.6 + -18.4
-27.6 + -18.4 = -46
-46w = -46
w = 1
Simplifying
W = 1
Step 1: Simplify both sides of the equation.
18.4+8w=6(9w−4.6)
18.4+8w=(6)(9w)+(6)(−4.6)(Distribute)
18.4+8w=54w+−27.6
8w+18.4=54w−27.6
Step 2: Subtract 54w from both sides.
8w+18.4−54w=54w−27.6−54w −46w+18.4=−27.6
Step 3: Subtract 18.4 from both sides.
−46w+18.4−18.4=−27.6−18.4 −46w=−46
Step 4: Divide both sides by -46.
−46w −46 = −46 −46
w=1
