Question

if 2y +7 =4 then y is​

Answer 1

Answer:

$y = \frac{ - 3}{2}$

Step-by-step explanation:

$2y + 7 = 4 \\ 2y = 4 - 7 \\ 2y = - 3 \\ y = \frac{ - 3}{2}$

Answer 2

Here,
2y+7=4
Or, 2y=4-7
Or, 2y=-3
Or, y= (-3/2)



// so if we want to prove it, it becomes;
2*(-3/2)+7=4
Or, -3+7=4 // both 2 got cancelled//
Or, 4=4, proved//
