To solve the equation 1/5 + 3/10 = 4/5 for x, we need to isolate x on one side of the equation.
1/5 + 3/10 = 4/5
To add fractions, we need the same denominator:
2/10 + 3/10 = 4/5
Combining the numerators:
5/10 = 4/5
Now, we can cross-multiply:
5 * 5 = 4 * 10
25 = 40
Since 25 is not equal to 40, the equation 1/5 + 3/10 ≠ 4/5 is not true.
1/5+3/10 x=4/5
