1. If R = 32 - 11 (OC+2y). then find R when: x=2 and y=4
Mice21 [21]

The correct equation says to find R = 32 - 11 (X+2y). This gives us the value of -78.

<h3>How to solve for the equation below</h3>

We have this

R = 32 - 11 (X+2y)

we have the following values for x and y as 2 and 4 respectively.

What we have to do would be to find the value of R after we have put in these values in the equation.

To do this, we would then have:

R = 32 - 11(2 + 2*4)

R = 32 -11(2+8)

R = 32 - 11 * 10

R = 32 - 110

This would give us the value that says

R = -78

Hence the value of R is given as -78
