5a - 2b + 3x - a + 7b - 12 - 5x

Put x = 3, a = -1 and b = 2

5(-1) - 2(2) + 3(3) - (-1) + 7(2) - 12 - 5(3)

-5 - 4 + 9 + 1 + 14 - 12 - 15

-9 + 24 - 27

Answer 2

Hi

Here's the answer

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\blue{S}\green{W}\purple{E}\orange{R}}}}\star$

(-12)

Step by Step explanation:

${\colorbox{pink}{First you will substitute the values of x, a and b}}$

5a - 2b + 3x - a + 7b - 12 - 5x

= (5*-1) - (2*2) + (3*3) - (-1) + (7*2) - 12 - (5*3)

= - 5 - 4 + 9 + 1 + 14 - 12 - 15

= - 9 + 24 - 27

= 24 - 36

= (-12)
