Question

100+x*20=240 60+360/x=100

Answer 1

100+х*20=240
100+х=240:20
100+х=12
х=100-12
х=88
---------------------
100+88*20=240

Answer 2

To solve the equations:

1. 100 + x * 20 = 240

Let's simplify this equation step by step:

100 + x * 20 = 240 Subtract 100 from both sides: x * 20 = 240 - 100 x * 20 = 140 Divide both sides by 20: x = 140 / 20 x = 7

So the value of x in the first equation is 7.

2. 60 + 360 / x = 100

Let's simplify this equation step by step:

60 + 360 / x = 100 Subtract 60 from both sides: 360 / x = 100 - 60 360 / x = 40 Multiply both sides by x: 360 = 40 * x Divide both sides by 40: x = 360 / 40 x = 9

So the value of x in the second equation is 9.

Therefore, the solutions to the given equations are x = 7 and x = 9.
