Question

What is the value of the expression below when y=8 and z=8? 10y-3z

Answer 1

Given :-

$\to\sf 10y - 3z \: when, y = 8 \: and \: z = 8$

To Find :-

$\to\sf Value \: of \: \boxed{\bf 10y - 3z}$

Solution :-

We have,

• 10y - 3z

Substituting the values of y and z,

$= \sf10 \times 8 - 3 \times 8$

$= \sf 80 - 24$

$= \bf56$

Hence, the value of 10y - 3z is 56

Answer 2

Answer:

• We have to find the value of 10y - 4z

Solution :

Given Values

• y = 8
• z = 8

Substituting these values in 10y - 3z

we get,

= 10 × 8 - 3 × 8

= 80 - 24

= 56

Hence

• value of 10y - 3z is 56
