Given the equation y=-3x+2.5: When x is 1, what value of y makes the equation true? When x is -1.5, what value of y makes the equation true? When y is 8.5, what value of x makes the equation true?

Step-by-step explanation:

when,X=1

y=-3 *1+2.5

y=-3+2.5

y=0.5

when,X=1.5

y=-3*1.5+2.5

y=-4.5+2.5

y=-2

when,y=8.5

8.5=-3*X+2.5

3*X=2.5-8.5

3*X=-6

X=-6/2

X=-3

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
