Rewrite the equation to isolate the variable.. df= g- 10 for d
Softa [21]
1) subtract 2 from both sides: y-2 = 9x +2 -2 y-2 = 9x 2) divide both sides by 9: (y-2)/9 = 9x/9 (y-2)/9=x

so it would be (g-10)/f

Solve for x.<br><br> x=<br><br> Look at image
postnew [5]

Answer:

x = 14

Step-by-step explanation:

To find x, the following equation is generated given the available information:

\frac{(x + 7) + x)}{x + 7} = \frac{12 + 8}{12}

\frac{2x + 7}{x + 7} = \frac{20}{12}

\frac{2x + 7}{x + 7} = \frac{5}{3}

Cross multiply

3(2x + 7) = 5(x + 7)

6x + 21 = 5x + 35

Collect like terms

6x - 5x = - 21 + 35

x = - 21 + 35

x = 14
