Question

135 : 5 + y = 542 X - 39 * 4 = 150 Y - 69 * 4 = 500 900 - x = 225 : 3

Answer 1

135:5+y=542

27+y=542

y=542-27

y=515

x-39×4=150

x-156=150

x=150+156

x=306

y-69×4=500

y-276=500

y=500+276

y=776

900-x=225÷3

900-x=75

-x=75-900

-x=-825

x=825

Answer 3

To solve these equations, let's go step by step:

1. 135: 5 + y = 542 Let's isolate y by subtracting 5 from both sides: y = 542 - 5 y = 537

2. X - 39 * 4 = 150 We'll simplify the equation: X - 156 = 150 Now, isolate X by adding 156 to both sides: X = 150 + 156 X = 306

3. Y - 69 * 4 = 500 Simplifying the equation: Y - 276 = 500 Isolating Y: Y = 500 + 276 Y = 776

4. 900 - x = 225 : 3 Dividing 225 by 3: 900 - x = 75 Now, isolate x by subtracting 900 from both sides: -x = 75 - 900 -x = -825 Multiply both sides by -1 to get x: x = 825

So the solutions to the given equations are: x = 825 y = 537 X = 306 Y = 776
