Which equation is in standard form 3x +4y=10 ,19 +3y =2x , 7y-7x =8 . 8 +5x =3y

Step-by-step explanation:

we know that

The standard form of a line is in the form

where

A is a positive integer, and B, and C are integers

Verify each case

case A) -------> is in standard form

case B) -------> is not in standard form

case C) -------> is not in standard form (the coefficient of x must be positive)

case D) -------> is not in standard form

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
