Question

0.7+0.9x=0.76x solve the equation​

Answer 1

$= > 0.7 + 0.9x = 0.76x \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: 0.7 = 0.76x - 0.9x \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: 0.7 = - 0.14x \\ = > \: \: - ( \frac{0.7}{0.14} ) = x \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = - ( \frac{7 \times 100}{14 \times 10} ) \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = -( \frac{1 \times 10}{2} ) \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \red{x = - 5}}$

Answer 2

Answer:

answer is -5

Step-by-step explanation:

7/10+9/10x=76x/100

(7+9x)1/10=76x/100

7+9x=76x×10/100

7+9x=76x/10

7=76x/10-9x

7=76x-90x/10

7=-14x/10

70=-14x

x=-70/14

x=-5
