Question

SOLVE THE FOLLOWING EQUATION

1.)
$8(x + 9) = 72$
------------------------------

2.)
$x - (2x + 5) = 7 - \frac{x}{2}$
------------------------------

3.)
$3(2t - 4) - 2(t + 3) = 5(t-1)$
​

Answer 1

Answer:

8x + 72 = 72

x= 8/72

x=9

this is 1st equation

x=2+5=7

this is 2nd equation

Answer 2

Answer:

see the explanation of first equation

Step-by-step explanation:

8(x+9) = 72

8x+72 = 72

8x = 72 - 72

8x = 0

x = 0/8

x = 8
