Find the non-extraneous solutions of square root of x+3-4=x-1

y = 2x-4

all the equations are the same as the slope-intercept form is the same for all the equations

Step-by-step explanation:

slope-intercept form:

2x-3 = y+1

i) move y to the left-hand side and change its sign

-y+2x-3 = 1

ii) move 2x-3 to the right-hand side and change its sign

-y = 1-2x+3

iii) add the numbers

-y = (1+3)-2x

-y = 4-2x

iv) change the signs on both sides of the equation

y = -4+2x

v) use the commutative property to reorder the terms

( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )

y = 2x-4
