Answer:

Answer is -32.

Step-by-step explanation:

a= -2

b=7

Expression: a(b2-a)

-2(7*2--2) (Place 'a' and 'b' values)

= -2(14+2) (Solve inside the bracket)

= -28-4 (Multiply -2 with the values inside the bracket)

= -32 (ans)

Thank you!!

Hope it helps!! (^-^)

Examine the system of equations.

Answer:

$\boxed{\boxed{\sf x=-3}}$

Step-by-step explanation:

$\sf y = -3x - 2$

$\sf y=7$

We'll substitute y into the equation:

$\sf 7 = -3x - 2$

Switch sides:

$\sf -3x-2=7$

Add 2 to both sides

$\sf -3x-2+2=7+2$

$\sf -3x=9$

Divide both sides by -3:

$\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}$

$\sf x=-3$

Therefore, the value of x/solution is -3
