X = 4/15 or 0.26
First add the numbers on the left side of the equation.
0.72 = 0.8 - 0.3x
Then move the variable to the left as well.
0.3x + 0.72 = 0.8
Move the constant to the right by subtracting.
0.3x = 0.8 - 0.72
Subtract the numbers
0.3x = 0.08
Divide both sides by 0.3.
And that should yield your answer.
Hope this helps. ^^

A
Step-by-step explanation:
Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13
