How do you solve #2h + 7= 3#?

Answer 1

Abigail Allen

#h = -2#

#2h + 7 = 3#

#2h + color(red)(cancel(color(black)(7) - 7)) = 3 color(red)(-7)#

#(color(red)(cancel(color(black)(2)))h)/color(red)(cancel(2)) = -4/color(red)(2)#

#color(blue)(h = -2)#

To solve the equation 2h + 7 = 3, you need to isolate the variable h.

Start by subtracting 7 from both sides of the equation: 2h + 7 - 7 = 3 - 7 2h = -4
Next, divide both sides of the equation by 2 to isolate h: 2h / 2 = -4 / 2 h = -2
