4 consecutive numbers that add up to 578

Step-by-step explanation:

You would need to form an equation to solve this

The equation would be: x + (x+1) + (x+2) + (x+3) = 578

Now you need to simplify it: 4x+6= 578

Bring the constants to one side: 4x = 572

Divide 4 on both sides: 4x/4 = 572/4

Simplify: x = 143

x = 143

x +1 = 143 +1 = 144

x + 2 = 143 + 2 = 145

x + 3 = 143 + 3 = 146

Checking the answer...

143 + 144 + 145 + 146 = 287 + 291 = 578

Hope this helps!!!

b would be 6xy
