Question

Express y in terms of x. Find the value of y when x = −1. 0.5y - 2 = 0.25x

Answer 1

Explanation:

step 1. 0.5y-2=0.25x

step 2 0.5 y-2=0.25(-1)

step 3 0.5y = 1.75

step 4 y = 3.5

Answer 2

y = 3.5

Explanation:

0.5y - 2 = 0.25x ( add 2 to both sides )

0.5y = 0.25x + 2 ( divide through by 0.5 )

y = 0.5x + 4

when x = - 1 , then

y = 0.5(- 1) + 4

= - 0.5 + 4

= 3.5
