Question

If x=8 and y=-3 evaluate 7(2x-3y)

Answer 1

Answer: 7(2x-3y)=175

Explanation:

Knowing that x=8 and y=3 we can sub them in to the expression and solve.

`7(2(8)-3(-3))\\7(16--9)\\7(25)\\175`

Answer 2

Explanation:

Plug in x = 8 & y = -3 in the expression

7(2x -3y) = 7(2*8 - 3*(-3))

= 7*( 16 + 9)

= 7 * 25

= 175
