3t - 7 = 5t, then 6t =

Answers

First, you would need to solve for t using the equation: 3t - 7 = 5t
Move all the numbers with variable on ones side
-7 = 5t - 3t
Combine like factors
-7 = 2t
Solve for t
-7/2 = t
After solving for t, you plug the answer into the equation you want to solve.
6 (-7/2) = -21
6*-7 = -42
-42/2 = -21
The answer is -21

Write an equation to represent the sentence.Nine times a number y subtracted from 85 is seven times the sum of four and y.

Answers

The equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation in the word is "Nine times a number y subtracted from 85 is seven times the sum of four and y"

Let the number is y:

The nine times a number = 9y

Subtract from 85:

85 - 9y

Seven times the sum of 4 and y = 7(4 + y)

Now on equating:

85 - 9y = 7(4 + y)

Thus, the equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).

Answer:

85 - 9Y = 7(4 + Y)

Step-by-step explanation:

Nine times a number Y. = 9 * Y = 9Y

subtracted From 85 = 85 - 9Y........... Equation 1

seven times sum of 4 and Y = 7(4 + Y)....... Equation 2

Equate Equation 1 and 2

85 - 9Y = 7(4 + Y)
