Answer:
1. 2x=5
Divide both by 2, x=2.5
2. y+1.8=14.7
Subtract 1.8 from both sides to isolate the variable, x=12.9
3. 6=1/2z
Multiply each side by 2 to isolate the variable, 12=z
4. 3 1/4 = 1/2+w
Isolate the variable by subtracting 1/2 to both sides, 2 3/4 = w
5. 2.5t=10
Divide each side by 2.5 to isolate the variable, t=4
