5h=85

200

2 less than the product of a number, x, and 4

4x-2

300

The quotient of a number, a, and 7 is no more than 23

a/7≤ 23

400

1 more than the product of 8 and a number, b, is at least 35

8b+1≥ 35

500

The product of 4 and the sum of a number, y, and 10 is 19

4(y+10)=19

Find x

-4x = 52

x = -13

200

m/5 = -7

m = -35

300

2(x+5) = -6

x = -8

400

4x-2x+3 = -2(x-1)

x = -1/4

500

-2x+6y= -4x+10 solve the equation for x.

x=-3y+5
