Question

5x-2=3 -5 + 4y = 9 solve the system of equiations

Answer 1

x=1 and y=7/2

Step-by-step explanation:

To solve this problem, isolate the term of x from one side of the equation.

5x-2=3 and -5+4y=9

5x-2=3

First, add by 2 from both sides.

5x-2+2=3+2

Solve.

3+2=5

Rewrite the problem down.

5x=5

Divide by 5 from both sides.

5x/5=5/5

Solve.

5/5=1

x=1

-5+4y=9

First, add by 5 from both sides.

-5+4y+4=9+5

Solve.

9+5=14

4y=14

Divide by 4 from both sides.

4y/4=14/4

Solve.

14/2=7

4/2=2

Rewrite as a fraction.

y=7/2

Dividing is another option.

7/2=3.5

y=7/2

Therefore, the correct answer is x=1 and y=7/2.

I hope this helps you! Let me know if my answer is wrong or not.

Answer 2

`x=1,y=(7)/(2)`

Step-by-step explanation:

Given the following question:


`5x-2=3`

`-5+4y=9`

To solve a system of equations we must start by solving the first equation for x, and then we substitute the value of x in in the second equation and then solve for y to find the value of both variables.



`5x-2=3`

`-5+4y=9`

`-2+2=0`

`3+2=5`

`5x=5`

`5x/5=x`

`5/5=1`

`x=1`

Substitute and solve the second equation:

`x=1`

`-5+4y=9`

`-5+5=0`

`9+5=14`

`4y=14`

`4y/4=y`

`(14)/(4) =(7)/(2)`

`y=(7)/(2)`

Your answers are "x = 1, and y = 7/2."

Hope this helps.
