Answer:

Explanation:

Solve 6x + 5(2x + 7) = 9x + 5

Isolate x (on the left) and solve for x

6x+10x+35 = 9x + 5 [ do not forget to distribute 5 to the 7]

6x+10x-9x=5-35

7x=-30

x=-30/7

or in mixed fraction

x=-4 2/7

Answer:

x = -30/7

Explanation:

6x + 5(2x + 7) = 9x + 5

Distribute

6x + 10x +35 = 9x+5

Combine like terms

16x +35 = 9x+5

Subtract 9x from each side

16x-9x +35 = 9x-9x+5

7x +35 = 5

Subtract 35 from each side

7x+35-35 = 5-35

7x = -30

Divide each side by 7

7x/7 = -30/7

x = -30/7
