The first part of the second line, she left the -5 there. The correct work and solution should be this: 5(2x-1)-3x=5x+9 <span><span>7x</span>−5</span>=<span><span>5x</span>+<span>9 </span></span>2x-5=9 2x=14 x=7
I think the expression for that is 13 • h • 3 because he gets $13 per hour and we don't know how many hours he worked so we would just put a variable and then he worked three times as many hours so multiply by 3. I might be wrong but hopefully it helps
