One Step with - and +

100

15 + b = 23

b = 8

200

x − 7 = 13

x = 20

300

m − 9 = 13

m = 22

400

−17 = x − 15

x = -2

500

-2 + x = 8

x = 10

Two Step 1 (positive)

100

9x + 1 = 82

x = 9

200

15 = 4m - 5

m = 5

300

103 = 9x + 13

x = 10

400

20 − 6v = 8

v = 2

500

10k + 9 = 89

k = 8

Two Step 2 (negative)

100

v/4 + 2 = -2

v = -16

200

−6 = n/2 − 10

n = 8

300

3 − 9v = 12

v = -1

400

−6 + x/4 = −5

x = 4

500

(x + 5)/6 = -1

x = -11

Challenge!

100

x − (-4) = 19

x = 15

200

x/5 = -40

x = -200

300

Solve means to........

find the value of the variable

400

-3x − 8 = -29

x = 7

500

-8.4 - 13.4x = -78.08

x = 5.2
