I'll mark has brainliest if answer correct...​​

Answer 1

Answer:

i) 3(t - 3) = 5(2t + 1)

=> 3t - 9 = 10t + 5

=> -14 = 7t

=> -2 = t

ii). 3x = 2x + 18

=> 3x - 2x = 18

=> x = 18

iii). 1.6 = y/1.5

=> 1.6 × 1.5 = y

=> 2.4 = y

Hence, Solved.

Answer 2

i.)

$\bf \large \implies \: 3(t - 3) \: = \: 5 \: (2t + 1)$

$\bf \large \rightarrow \: 3t \: - \: 9 \: = \: 10t \: + \: 5$

$\bf \large \rightarrow \: - 5 \: - 9 \: = \: 10t \: - \: 3t$

$\bf \large \rightarrow \: - 14 \: = \: 7t$

$\bf \large \rightarrow \: \frac{ - 14 \: }{ \: \: \: 7 \: } \: = \: t$

$\bf \large \rightarrow \: \cancel\frac{ - 14 \: \: \: ^{2} \: }{ \: \: \: 7 \: \: \: } \: = \: t$

$\bf \large \rightarrow \: \: 2 \: = \: t$

ii.)

$\bf \large \implies \: 3x \: = \: 2x \: + \: 18$

$\bf \large \rightarrow \: \: 3x \: - \: 2x \: = \: 18$

$\bf \large \rightarrow \: \:x \: = \: 18$

iii.)

$\bf \large \implies \: \: 1.6 \: = \: \frac{y}{1.5}$

$\bf \large \rightarrow \: \:y \: = \: 1.5 \: \times \: 1.6$

$\bf \large \rightarrow \: \:y \: = \: 2.4$
