C. Write the following linear equation in one variable in its standard form ax + b = 0.
1. 3x = 10
a.3x + 10 = 0
b.3x - 10 = 0
c.- 3x + 10 = 0
d.- 3x - 10 = 0
2. 5x – x – 7 = 6
a.6x + 13 = 0
b.6x - 13 = 0
c.4x + 13 = 0
d.4x - 13 = 0
3. 11x – 9 = 1
a.11x - 8 = 0
b.11x + 8 = 0
c.11x - 10 = 0
d.11x + 10 = 0
4. x + 2 + 7x – 12 = 0
a.8x - 14 = 0
b.8x + 14
c.8x - 10 = 0
d.8x + 10 = 0
5. 9x – x + 13 = 8 + 2x
a.10x - 21 = 0
b.10x + 21 = 0
c.6x - 5 = 0
d.6x + 5 = 0
