Question

1. Construct a one-solution linear equation with x = 4, a=5 and b = 15.1.)5x + 15 = 202.)4x + 5 = 153.)5x +4=154.)5x + 15 = 35

Answer 1

4) 5x + 15 = 35

Step-by-step explanation

We're looking for an equation with the form:

`y=ax+b`

If we want this to have only one solution we have to give y a value. This value can be found since we're already given the solution x = 4:

`y=5x+15`

replacing x:

`\begin{gathered} y=5\cdot4+15 \\ y=20+15 \\ y=35 \end{gathered}`

Therefore the one-solution linear equation we can construct with this information is:

`5x+15=35`
