Let's translate from English into math:

Eight times: 8*?

the sum of a number and 5: x+5

is 7: = 7

Now put it together in an equation: 8(x+5)=7

To solve this equation, first distribute the 8:

8x +40 = 7

Then subtract 40 from both sides:

8x=-33

Finally, divide by 8:

x=-33/8

Check your solution!

8*(-33/8+5) = -33 + 40 = 7 :-)
