1. Identify the error in generating an expression equivalent to4 + 2.c 1 (10 – 4x) Step 1: 4 + 2x + 3(10+ -41) Step 2: 4 + 2 + 5 + 2. Step 3: 4 + 2r - 5 + 2x Step 4: 1 Which step contains an error? Step 1 O Step 2 O Step 3 o Step 4 2. Explain the error and how you would correct it. Type your response in the space below.​

the first one

step-by-step explanation:

just id the test.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
