Write an expression to represent four more than the problem of three and a number z
kicyunya [14]

Answer:

If the "problem of 3 and a number z" is multiplying: 4+(3z)

If it's about adding: 4+(3+z)

Step-by-step explanation:

Scenario A: If it's 3 and z, then that means it's 3z, and we're adding 4, so it's 4+(3z) (make sure to put () around the 3z!)

Scenario B: If 3 and z is also 3+z, then the equation is 4+(3+z) (also use () on this too!)

How do I solve 2/3x-1=-3
Lostsunrise [7]
First of all you’d add 1 to both sides hence the -1, to get 2/3x=-2. then multiply both sides by the reciprocal of 2/3 which is 3/2. the left cancels out to get x and the right multiplies to get -3. so your answer is x=-3
