Question

3.7 + 2.5x = 4.5x - 12.3

Answer 1

`\begin{gathered} \text{We will solve for x} \\ 3.7+2.5x=4.5x-12.3\text{, we will ad 12.3 to both sides} \\ 3.7+2.5x+12.3=4.5x-12.3+12.3,\text{ reorder the sum and do the addition} \\ 3.5+12.3+2.5x=4.5x \\ 16+2.5x=4.5x\text{, now we substract 2.5x to both sides} \\ 16+2.5x-2.5x=4.5x-2.5x \\ 16=2x\text{ we divide by 2 in both sides} \\ (2x)/(2)=(16)/(2) \\ x=8 \\ \text{ } \\ So\text{ the solution is x=8} \end{gathered}`
