Step-by-step explanation:
<u>x-8</u><u>=</u><u>3</u><u>7</u><u>-</u><u>4</u>
<u>x</u><u>+</u><u>4</u><u>x</u><u>=</u><u>3</u><u>7</u><u>+</u><u>8</u>
<u>5</u><u>x</u><u>=</u><u>4</u><u>5</u>
<u>x</u><u>=</u><u>4</u><u>5</u><u>/</u><u>5</u>
<u>x</u><u>=</u><u>9</u>
Answer:
It simplifies to 2x + 2.
Let the number be x, then the expression is
x + 5 + (x - 3)
= x + 5 + x - 3
= x + x + 5 - 3
= 2x + 2.
