Question

5x+ 3 / 9-x = 7 solve equation​

Answer 1

Step-by-step explanation:

Simplifying 5x + 3 = -9x + -7 Reorder the terms: 3 + 5x = -9x + -7 Reorder the terms: 3 + 5x = -7 + -9x Solving 3 + 5x = -7 + -9x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9x' to each side of the equation. 3 + 5x + 9x = -7 + -9x + 9x Combine like terms: 5x + 9x = 14x 3 + 14x = -7 + -9x + 9x Combine like terms: -9x + 9x = 0 3 + 14x = -7 + 0 3 + 14x = -7 Add '-3' to each side of the equation. 3 + -3 + 14x = -7 + -3 Combine like terms: 3 + -3 = 0 0 + 14x = -7 + -3 14x = -7 + -3 Combine like terms: -7 + -3 = -10 14x = -10 Divide each side by '14'. x = -0.7142857143 Simplifying x = -0.7142857143

Answer 2

Answer:

x = -3/9

Step-by-step explanation:

5x+3/9-x=7

7(5x+3)=9-x

35x+21=9-x

35x+x=9-21

36x=-12

x=-12/36

x=-3/9
