Question

solve:
4 a-5 = 1
8 -2a = 2​

Answer 1

Answer:

$4a - 5 = 1 \\ \\ = \geqslant 4a = 1 + 5 \\ \\ = \geqslant 4a = 6 \\ \\ = \geqslant a = \frac{6}{4} \\ \\ = \geqslant a = \frac{3}{2}$

$8 - 2a = 2 \\ \\ = \geqslant - 2a = 2 - 8 \\ \\ = \geqslant - 2a = - 6 \\ \\ = \geqslant a = \frac{ - 6}{ - 2} \\ \\ = \geqslant 3$

Answer 2

Answer:

1. 4a= 1+5

4a=6

a=6/4

a=3/2

2. - 2a= -8+2

-2a = -6

a=-6/-2

a=3
