If x = 2y + 3 and 3x = 7 - 4y, what does x equal?

x = 17/5

Step-by-step explanation:

Plug in 2y + 3 as x in the second equation and solve for y to get 1/5

Then plug in y into the first equation and solve for x to get 17/5

Step-by-step explanation:

x=2y+3

3x=7-4y

Rearrange the numbers so they compare,

x=2y+3

3x=-4y+7

Multiply the first equation by 2 (this is so the variable with y matches in both equations)

2x=4y+6

3x=-4y+7

Add the two equations together

2x=4y+6

+

3x=-4y+7

5x=13

Divide both sides by 5 to isolate x

x=13/5

Simply the equation

x=2 3/5
