Answer:
x = [tex]\frac{92}{9}[/tex] or as a decimal 10.22
Step-by-step 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:
[tex]\frac{9x}{9} = \frac{92}{9}[/tex]
x = [tex]\frac{92}{9}[/tex] or as a decimal 10.22
Hope this helps!
