I need help solving this and finding the solution

Answer 1

can you screenshot the steps

Answer 2

4x + 3x = 7

Answer 3

4x + y = 7
y = 3x

x = 1
Y= 3

Answer 4

x = 1

Answer 5

4 + 3 = 7

Answer 6

how did you guys get the answers

Answer 7

4x + 3x = 7
7x = 7

x 7/7

x=1

Answer 8

Y= 3

Answer 9

Alright give me a second.

Answer 10

So first off you need to replace the y=3x equation in for the "y" value of the first equation.
4x+3x=7

Next you'd need to solve for x (but first, simplify it).
4x+3x = 7x
7x = 7

Now you just divide both sides by 7 to get x by itself.
\(\sf{\dfrac{7x}{7}}\) = \(\sf{\dfrac{7}{7}}\)

This means that x would be equal to 1 since 7 divided by 7 is 1.
