How do you solve #y+9.4=-12.2#?

Answer 1

#y=-21.6#

Given #y+9.4=-12.2#, we need to isolate #y# to find its value.

Subtract 9.4 from both sides: #y\cancel(+9.4)\cancel(\color(red)(-9.4))=-12.2\color(red)(-9.4)# Simplify to #y=-12.2-9.4# Combine the subtraction and you get #y=-21.6#

To solve the equation (y + 9.4 = -12.2), you need to isolate (y) by performing the inverse operation. Subtract 9.4 from both sides of the equation.

(y + 9.4 - 9.4 = -12.2 - 9.4)

(y = -12.2 - 9.4)

(y = -21.6)
