Answer:
X=-300000
Step-by-step explanation:
Move variable to the left-hand side
1200+0.005x-0.0015x=1500
Move the constant to the right-hand side and change sign
0.005x-0.0015x=1500-1200
Combine like terms
-0.001x=1500-1200
Subtract the numbers
-0.001x=300
Divide both sides of the equation by -0.001
X=-300000
Answer:
5800 x 0.0135 = 78.3
78.3 x 3 =234.9
78.3/2 = 39.15
234.9 + 39.15 = 274.05
Your answer is 274.05
