Question

3x+x=20,2a+a=48,6m-m=25,4r-r=12

Answer 1

3x+x=20
4x=20
X=20/4
X=5

2a+a=48
3a=48
A=48/3
A=16

6m-m=25
5m=25
M=25/5
M=5

4r-r=12
3r=12
R=12/3
R=4

Answer 2

Let's solve each equation step-by-step:

1. 3x + x = 20 Combining like terms on the left side: 4x = 20 Now, isolate x by dividing both sides by 4: x = 20 / 4 x = 5

2. 2a + a = 48 Combining like terms on the left side: 3a = 48 Now, isolate a by dividing both sides by 3: a = 48 / 3 a = 16

3. 6m - m = 25 Combining like terms on the left side: 5m = 25 Now, isolate m by dividing both sides by 5: m = 25 / 5 m = 5

4. 4r - r = 12 Combining like terms on the left side: 3r = 12 Now, isolate r by dividing both sides by 3: r = 12 / 3 r = 4

So, the solutions for each variable are: x = 5 a = 16 m = 5 r = 4
