Answer to Q6:
x = 3
Step-by-step explanation:
Given equation is :
7x = 6+5x
We have to find the value of x by simplifying above equation.
Adding -5x to both sides of above equation, we get
7x-5x = 6+5x-5x
Adding like terms, we have
2x = 6+0
2x = 6
Dividing by 2 to both sides of above equation, we get
2x/2 = 6/2
x = 3 Which is the answer.
Answer to Q7:
x = 6
Step-by-step explanation:
We have given an equation.
30 = 4x+6
We have to find the value of x.
Adding -6 to both sides of above equation , we get
30-6 = 4x+6-6
24 = 4x+0
24 = 4x
Dividing by 4 to both sides of equation, we have
24/4 = 4x/4
6 = x
Swapping equation , we have
x = 6 which is the answer.
Answer to Q8:
x = 4
Step-by-step explanation:
Given equation is:
2(x+4) = 16
We have to find the value of x by simplifying it.
Distributing 2 to parentheses of above equation, we get
2x+8 = 16
adding -8 to both sides of above equation, we have
2x+8-8 = 16-8
2x+0 = 8
2x = 8
dividing by 2 to both sides of above equation, we have
2x/2 = 8/2
x = 4 which is the answer.
Answer to Q8:
x = 3
Step-by-step explanation:
We have given following equation.
7+5x = 3x+13
We have to find the value of x by simplifying above equation.
Adding -3x to both sides of above equation, we get
7+5x-3x = 3x+13-3x
adding like terms, we get
7+2x = 13
adding -7 to both sides of above equation, we get
-7+7+2x = -7+13
2x = 6
dividing by 2 to both sides of above equation , we have
2x/2 = 6/2
x = 3 which is the answer.
