Question

Use inverse operations to solve each equation.

1) -2x=34?_____

2) y-3.5=-2.1?______

3) 2/3z= -6?_______

Plz help me! I'm confuse, I will be extremely grateful if you help me!!

Answer 1

1) -2x = 34
The inverse of multiplication is division, so divide both sides by -2.
x = -17

2) y - 3.5 = -2.1
The inverse of subtraction is addition, so add 3.5 to both sides.
y = 1.4

3) 2/3z = -6
The inverse of division is multiplication, so multiply both sides by 3z
2 = -18z
z = -1/9
