(−1.2,3.3)

(−2.4,−6.6)
left parenthesis negative 2.4 comma negative 6.6 right parenthesis

(2.4,−6.6)
left parenthesis 2.4 comma negative 6.6 right parenthesis

(−2.4,6.6)

Answer 1

Solve 2/3 x − 5 = 7/3 x − 1.
−4 = (5/3)x → x = −4·3/5 = −12/5 = −2.4.
y = (2/3)(−2.4) − 5 = −1.6 − 5 = −6.6.

So (−2.4, −6.6) is the solution.
