Answer:

x =
(92)/(9) or as a decimal 10.22

Explanation:

Step 1 - Put them both into an equation in which it totals 90:

2x - 6 + 7x + 4 = 90

Step 2 - Add the like variables together:

2x + 7x -6 + 4

9x -2 = 90

Step 3 - Add two to each side:

9x -2 + 2 = 90 + 2

9x = 92

Step 4 - Divide both sides by 9 to find x:

(9x)/(9) = (92)/(9)

x =
(92)/(9) or as a decimal 10.22

Hope this helps!
