Answer:
x = 13/4
Step-by-step explanation:
(2x/3)-(5/3)=(1/2)
Multiply everything by 3
2x - 5 = 3/2
Get the x term on it's own by adding 5 to both sides
2x = 3/2 + 5
2x = 3/2 + 10/2
2x = 13/2
Divide by 2 to get x on it's own
x = 13/2 ÷ 2 = 13/2 * 1/2 = 13/4

Answer:
Step-by-step explanation:
Simplifying
8x + 5y = 27.15
Solving
8x + 5y = 27.15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
8x + 5y + -5y = 27.15 + -5y
Combine like terms: 5y + -5y = 0
8x + 0 = 27.15 + -5y
8x = 27.15 + -5y
Divide each side by '8'.
x = 3.39375 + -0.625y
Simplifying
x = 3.39375 + -0.625y
