Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only
olga2289 [7]

Answer:

4 \frac{1}{9}x + 12\frac{1}{3} = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = -1\frac{1}{3} + \frac{2}{9} x

Therefore...

5x - 4y + 7 = 0

5x - 4(-1\frac{1}{3} + \frac{2}{9} x) + 7 = 0

5x + 5\frac{1}{3}  - \frac{8}{9} x + 7 = 0

4 \frac{1}{9}x + 12\frac{1}{3} = 0

10. Solve:6 - 2(x + 6) = 3x +4<br> x = -2<br> x = 2<br> x=-10<br> x = 10
ololo11 [35]

Answer:

x = -2

Step-by-step explanation:

6 - 2(x + 6) = 3x +4

6 -2x - 12 = 3x + 4

6 - 12 - 2x = 3x + 4

-6 -2x = 3x +4

-6 - 4 - 2x = 3x + 4 - 4

-10 -2x = 3x

-10 -2x + 2x = 3x + 2x

-10 = 5x

-10 / 5 = 5x/5

x = -2

I hope this helps!!
