Asystem of equations is shown below: equation a: 4c = d – 8 equation b: c = 5d + 8 which of the following steps should be performed to eliminate variable d first?

a. multiply equation b by 4.
b. multiply equation a by –5.
c. multiply equation a by 4.
d. multiply equation b by 5.

5/20 so 25%

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
