Question

For the equation 5x + 8y = 50, if y = 10, then the value of x is: a) 6 b) – 6 c) 12 d) -12

Answer 1

X=-6

Step-by-step explanation:

if 5x+8y=50

and y=10 then putting the value of y in the eq.we get

5x+8(10)=50

5x+80=50

5x=-30

x= -6

Answer 2

Answer:

x = -6(b)

Step-by-step explanation:

5x + 8y = 50

y = 10

5x + 8(10) = 50

5x + 80 = 50

5x = 50 - 80

5x = -30

divide both sides by 5

5x/5 = -30/5

∴x = -6 option b
