Question

Find the value of x so that the ordered pair (x, 7) satisfies the equation y = 4x - 5. *

Answer 1

x=3

Step-by-step explanation:

Given the equation:

`y=4x-5`

In the ordered pair, (x,7): y=7

`\begin{gathered} \implies7=4x-5 \\ 7+5=4x \\ 12=4x \\ x=(12)/(4) \\ x=3 \end{gathered}`

The value of x so that the ordered pair (x, 7) satisfies the equation y=4x-5 is 3.
