Check all the equations that corresponds to this word problem.

•  $\frac{3}{4}x\ -18\ =\ \frac{1}{2}x+5$  

•  $-18\ +\frac{3}{4}x\ =\ 5\ +\ \frac{1}{2}x$  

•  $-\frac{3}{4\ }x\ +18\ =\ \frac{1}{2}x\ +\ 5$  

•  $18-\frac{3}{4}x\ =\frac{1}{2}x\ +5$  

Choose all the equations that correspond to this word problem.

• 155 + 10x = 230 - 15x

• 10x + 155 = -15x + 230

• 230 - 15x = 155 + 10x

• -15x + 230 = 10x _155
