Question

0.7(1.5 + y) = 3.5y - 1.47

Answer 1

y = 0.9

Explanation:

1.05 + 0.7y = 3.5y - 1.47

-3.5y + 0.7y = -1.47 - 1.05

-2.8y = -2.52

y = 9/10 = 0.9

Answer 2

`\textbf{HELLO!!}`

`0.7\left(1.5+y\right)=3.5y-1.47`

`1.05+0.7y=3.5y-1.47 \gets \textsl{Expand}`

`1.05+0.7y-1.05=3.5y-1.47-1.05 \gets Subtract\; 1.05 \from\:both\:sides`

`0.7y=3.5y-2.52`

`0.7y-3.5y=3.5y-2.52-3.5y`

`\mathrm{Subtract\:}3.5y\mathrm{\:from\:both\:sides} \\warrow`

`-2.8y=-2.52`

`(-2.8y)/(-2.8)=(-2.52)/(-2.8) \hookleftarrow \mathrm{Divide\:both\:sides\:by\:}-2.8`

`\boxed{\boxed{\underline{\textsf{\textbf{y=0.9}}}}}`

`\bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet \bullet`

`\textbf{HOPE IT HELPS}`
