Answer:

x = 12

Step-by-step explanation:

This is a multi-step equation.

The first thing we can do is add 9 to both sides, eliminating the -9 from the left side of the equation. Now we have 7x = 84.

You can divide 84 over 7x to get a total of x =12.

Answer:

x = 12

Step-by-step explanation:

Step 1: Add 9 to both sides.

  • 7x - 9 + 9 = 75 + 9
  • 7x = 84

Step 2: Divide both sides by 7.

  • \frac{7x}{7} = \frac{84}{7}
  • x = 12

Step 3: Check if solution is correct.

  • 7(12) - 9 = 75
  • 84 - 9 = 75
  • 75 = 75

Therefore, x = 12.

Let 2x-5y=16 and 5x+3y=9. what is the value of 12x+y
kari74 [83]
2x-5y=16    =>10x-25y=80
5x+3y=9     => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34
