3^2(6-2)*(4-6)/3
=(9*4)*(-2/3)
=36*(-2)/3
= -72/3
= -24 (answer)
Solve the first equation for y
Substitute the given value of y into the equation -5x-y=21
When there is a - in front of an expression in parentheses, change the sign of each term in the expression
Collect like terms
Move the constant to the right-hand side and change its sign
Add the numbers
Divide both sides of equation by -3
Substitute the given value of x into the equation y=4x+6
Multiply the numbers
Calculate the difference
The possible solution of the system is the ordered pair (x,y)
-2+4-3+8-2-0.5 = -7.5+12
-7.5+12 = 4.5
4.5/6 (number of months) = 0.75
0.75 = -3/4
-3/4 is your answer. :)
