Answer:

x = 5/6

Explanation:

Cross multiply.

18(x - 2) = 3(-7)

Divide both sides by 3.

6(x - 2) = -7

Distribute the 6.

6x - 12 = -7

Add 12 to both sides.

6x = 5

Divide both sides by 6.

x = 5/6

Answer: x = 5/6

Answer :


\dashrightarrow\:\:\sf (x - 2)/(3) = (-7)/(18) \\ \\ \\


\dashrightarrow\:\:\sf (x - 2) * 18= -7 * 3 \\ \\ \\


\dashrightarrow\:\:\sf 18x - 36 = -21 \\ \\ \\


\dashrightarrow\:\:\sf 18x = -21 + 36\\ \\ \\


\dashrightarrow\:\:\sf 18x = 15\\ \\ \\


\dashrightarrow\:\:\sf x = (15)/(18) \\ \\ \\


\dashrightarrow\:\:\sf x = (5)/(6) \\ \\ \\


\dashrightarrow\:\: \underline{ \boxed{\textsf{\textbf{x $\approx$ 0.84}}}}\\ \\ \\
