0.6x - 18 = 00.7x = 78x - 5 = x - 40
To solve these equations:
0.6x - 18 = 0Add 18 to both sides:0.6x = 18Divide by 0.6:x = 30
0.7x = 7Divide by 0.7:x = 10
8x - 5 = x - 40Subtract x from both sides:7x - 5 = -40Add 5 to both sides:7x = -35Divide by 7:x = -5
Therefore, the solutions to the equations are x = 30, x = 10, and x = -5.
0.6x - 18 = 0
0.7x = 7
8x - 5 = x - 40
To solve these equations:
0.6x - 18 = 0
Add 18 to both sides:
0.6x = 18
Divide by 0.6:
x = 30
0.7x = 7
Divide by 0.7:
x = 10
8x - 5 = x - 40
Subtract x from both sides:
7x - 5 = -40
Add 5 to both sides:
7x = -35
Divide by 7:
x = -5
Therefore, the solutions to the equations are x = 30, x = 10, and x = -5.
