Problem
\[ \text { C } x=2 \text { or }-3 \frac{1}{3} \] \[ \text { D } x=1 \frac{1}{9} \] 4 Solve \( \frac{2}{3} x+5=-7 \) A \( x=-18 \) \( B x=-3 \) C \( x=3 \) D \( x=18 \) 5 Solve \( 3 x+2>8 \) A \( x>10 / 3 \) \( B x<2 \) \( C x<-2 \) D \( x>2 \)
Solution
Step 1 ：\( \frac{2}{3} x+5=-7 \) Subtract 5 from both sides: \( \frac{2}{3} x=-12 \)
Step 2 ：Multiply both sides by 3/2: \( x=-18 \)
Step 3 ：\( 3 x+2>8 \) Subtract 2 from both sides: \( 3x>6 \)
Step 4 ：Divide both sides by 3: \( x>2 \)
