Which system of equations has infinitely many solutions? a. 4x + 2y = 5 -4x - 2y = 1 b. -10x + y = 4 10x - y = -4 c. -8x + y = 2 8x - y = 0 d. -x + 2y = 6 7x - 2y = 12

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

∠cbe and ∠deb are same-side interior angles.
