Question

15) John has $25 more in his account than Jess. Jess has $35. Write and solve an equation to represent how much John has in his account.

Answer 1

hello

to solve this question, we need to write out an equation to relate both accounts

first of all,

let John be represented by x

let Jess be represented by y

from the question, John has $25 in his account more than Jess.

we can write that out as

`x=y+25`

the equation to represent John's account is written as x = y + 35

but we already know what Jess has in his account?

we can simply substitute the value into the equation and solve for x

`\begin{gathered} y=35 \\ x=y+25 \\ x=35+25 \\ x=60 \end{gathered}`

from the calculations above, John has $60 in his account
