a. ×=5×-13

b. 9×-4=2×

c. ×+5×=-10+3

d. 4×-5×-9-3×+4×

e. 3×-8×+9×=12-7×
​

Answer 1

a. ×=5×-13

13 = 5x - x

13 = 4x

x = 13/4

b. 9×-4=2×

9x - 2x = 4

7x = 4

x = 4/7

c. ×+5×=-10+3

6x = -7

x = -7/6

d. 4×-5×-9-3×+4×

-x - 9 - 3x + 4x

-4x - 9 + 4x

-9

e. 3×-8×+9×=12-7×

-5x + 9x = 12 - 7x

4x = 12 - 7x

4x + 7x = 12

11x = 12

x = 12/11
