Question

Evaluate 5y − 3z + 6, when y = 10 and z = 4

Answer 1

The answer to the equation 5y - 3z + 6 is answer choice B or 44.

Explanation:

How can we solve this?

The first step is writing what we know.

Equation: 5y - 3z + 6

y = 10

z = 4

Since we know what y and z are, we know we have to use substitution.

`5y-3z+6`

`5(10)-3(4)+6` Substitute the values in for y and z.

`50-3(4)+6` Multiply 5 and 10 together.

`50-12+6` Multiply -3 and 4 together.

`38+6` Subtract 50 and 12

`44`
