Is it supposed to be 3*2+4x=1 (The star means to multiply). If so do the following.

3*2+4x=1
Multiply 3*2
6+4x=1
Subtract 6 from both sides
4x= -5
Divide by 4
x= -1.25

Over here.. We have to make x as the subject.
Which means...You'd have to multiply 3 and 2 which is 6...6+4x=1 After which you shift 6 to the other side... 4x=1 -6 ..Whixh concludes 4x is ...Wait.. is there an error in the question?.. Shouldn't it be 3x+2+4x=1?

Complete the missing value in the solution to the equation: 7 + 5x = =3(y-2) ( ,5)

mafiozo [28]

Answer:

x = 2/5

Step-by-step explanation:

Given:

7 + 5x = 3(y-2)

Rearrange this equation such that x is expressed in terms of y

7 + 5x = 3(y-2) (expand right side)

7 + 5x = y(3)-2(3)

7 + 5x = 3y-6 (subtract 7 from both sides)

5x = 3y - 6 - 7

5x = 3y - 13

we are given the y-value of the coordinate pair (? , 5)

simply substitute y=5 into the equation above

5x = 3y - 13

5x = 3(5) - 13

5x = 15 - 13

5x = 2 (divide both sides 5)

x = 2/5
