Question

X + 3x + 3x + o.8 = 7. 7​

Answer 1

7x + 0.8 = 7,7
7x=7,7 -0,8
7x=6,9
x= 69/70

Answer 2

To solve the equation, let's combine like terms on the left side:

X + 3x + 3x + 0.8 = 7

This simplifies to:

7x + 0.8 = 7

Next, we'll isolate the variable term on one side by subtracting 0.8 from both sides:

7x + 0.8 - 0.8 = 7 - 0.8

This gives us:

7x = 6.2

Finally, we'll solve for x by dividing both sides of the equation by 7:

(7x)/7 = 6.2/7

x = 6.2/7

x ≈ 0.8857
