Answer:

(7/8, 5.25)

Step-by-step explanation:

4x+2y=14

subtract 4x to turn equation into slope intercept form

so, it would be 2y=-4x+14

divide by 2

y=-2x+7

substitute answer into original equation

4x+2(2x+7)=14

4x+4x+7=14

8x+7=14

subtract 7 from 14

8x=7

divide by 8

x= 7/8

plug in for x

y= -2(7/8)+7

y=5.25
