Answer: x=2

Step-by-step explanation:

1. Regroup terms.

1+4x=7x-5

2. Subtract 4x from both sides.

1=7x-5-

3. Simplify 7x-5-4x to 3x-5.

1=3x-5

4. Add 5 to both sides.

1+5=3x1+5=3x

5. Simplify 1+5 to 6.

6=3x

6. Divide both sides by 3.

3/6=x

7 Simplify 3/6 to 22.

2=x

8 Switch sides.

1+4.x= -5+7.x
you take the 1 and -5 add them
= -4
then you have the 4.x and the 7.x
the x’s leave them subtract 4 from 7
it’s 3x now
so now you have -4=3x
divide and you will have what x equals

X=y-1 y=(4-2x) solve by substition

Nataliya [291]

Since you have an equation equal to both x and y, you can either substitute the equation equal to x for x or the equation equal to y for y.
x=y-1
y=4-2x
I would substitute the y in using 4-2x
x=(4-2x)-1
x=3-2x
3x=3
x=1
Then plug in x and solve for y
1=y-1
2=y
