How do you solve #16x + 36= 7x#?

Answer 1

Kennedy Adams

#x=-4#

Place the number on one side and all the variables on the other.

#16x +36 color(red)(-36)color(blue)(-7x) = 7x color(blue)(-7x) color(red)(-36)#

#16x -7x = -36#

#9x= -36#

#x = -4#

To solve the equation 16x + 36 = 7x, you first need to isolate the variable x on one side of the equation.

Step 1: Subtract 7x from both sides: 16x + 36 - 7x = 7x - 7x 9x + 36 = 0

Step 2: Subtract 36 from both sides: 9x + 36 - 36 = 0 - 36 9x = -36

Step 3: Divide both sides by 9 to solve for x: 9x/9 = -36/9 x = -4
