Question

Find the value of a and of b in the following: -2 (a b) + (-5 8) = (7 3)

Answer 1

Answer:

a=-6 and b =5/2

Step-by-step explanation:

multiply the -2

(-2a -2b) + (-5 8) = (7 3)

now add the x coordinate nd y coordinate and compare

X coordinate.

-2a-5= 7

12=-2a

a= -6

y coordinate

-2b+8=3

-2b=-5

b=5/2
