Question

Substitute x with (-2) and y with (-4)
Simplify: 5(41 - x) + {-7(y + x)} =

Answer 1

`257`

Explanation:

We want to evaluate:

`5(41 - x) + ( - 7(y + x)`

for x=-2 and y=-4.

We substitute to get:

`5(41 - - 2) + ( - 7( - 4 + - 2)`

We now simplify to get:

`5(41 + 2) - 7( - 6)`

`5 * 43 + 42`

`215 + 42 = 257`
