Answer: x= 7

Step-by-step explanation:

4x-7= -3x First add -3x on both sides

+3x +3x

7x -7 = 0

+7 +7 add 7 to both sides

7x = 7

x = 1 divide both sides by 7

Answer:

x = 1

Step-by-step explanation:

1. Add 3x to both sides of the problem

4x + 3x - 7 = -3x + 3x
-3x + 3x cancels out and leaves us with zero
7x - 7 = 0

2. Add 7 to both sides

7x (- 7 + 7) = 0 + 7
-7 + 7 cancels out
7x = 7

3. Divide both sides by 7

7x/7 = 7/7
x = 1

To make sure our answer is correct we can plug in 1 to x in the problem

4(1) - 7 = -3(1)
4 - 7 = -3 : True

17/20 equals t plus -13/20 solve for t

docker41 [41]

The value of t is 3/2 or 1.5

Step-by-step explanation:

The given expression is 17/20 equals t plus -13/20.

Changing it into an equation form :

⇒ t + (-13/20) = 17/20

Keeping t alone on one side and constant terms to the another side,

t = (17/20) + (13/20)

Since the denominators are same, it is easy to simplify those fractions.

⇒ t = (17+13)/20

⇒ t = 30/20

⇒ t = 3/2

⇒ t = 1.5

The solution is t= 3/2 or t= 1.5
